The frontier between Afghanistan and Pakistan runs for roughly 2,600 kilometers across some of the most broken terrain on the planet, and for the better part of half a century it has functioned less as a national boundary than as a single ungoverned theater that two states pretend to divide. The line on the map carries the name of a British colonial administrator. The reality on the ground is a continuous belt of mountains, valleys, smuggling trails, refugee corridors, and militant sanctuaries that no fence has ever fully sealed. Anyone trying to understand how violence aimed at India is produced, sustained, and refreshed has to reckon with this belt, because the threat that reaches Kashmir and the Indian heartland does not originate at the Line of Control. It originates much further west, in a zone where the writ of the Pakistani state thins out, the writ of the Afghan state has effectively dissolved into Taliban rule, and a jihadist ecosystem older than most of the men who staff it keeps regenerating itself.

This region rarely sits at the center of the targeted-killing story. The eliminations that have defined India’s covert campaign happened in Karachi apartments, Lahore mosques, Rawalakot prayer halls, and Sialkot streets, not in the Hindu Kush. Yet the Afghan frontier belongs in any honest account of the shadow war for a reason that is structural rather than incidental. The men who were eventually shot in Pakistani cities were, in many cases, products of this belt. They trained in camps that the Afghan jihad of the 1980s first established. They absorbed an ideology that crossed and recrossed the mountains for four decades. They moved through a corridor that no government has ever controlled, and they belonged to organizations whose survival depends on the strategic depth that Afghanistan provides. To map the safe haven and ignore the country next door would be to study a body without acknowledging its bloodstream.

The argument of the analysis that follows is deliberately precise, and it resists the two lazy positions that dominate public commentary. The first lazy position holds that Taliban-ruled Afghanistan is a direct sponsor of anti-India terrorism, a forward base from which Kashmir-focused groups plot attacks on New Delhi. The second lazy position holds the opposite, that the Taliban government has no interest in India, that the frontier is purely Pakistan’s problem, and that Afghan instability is therefore irrelevant to Indian security. Both readings are wrong, and they are wrong in instructive ways. Afghanistan under the Taliban is not a sanctuary built specifically for India-focused terrorism. It is something more dangerous and harder to counter: a petri dish for the broader jihadist ecosystem that anti-India terrorism feeds on. The Haqqani network, the Tehreek-e-Taliban Pakistan, the Islamic State’s Khorasan branch, and the residue of al-Qaeda all operate from Afghan soil. Their activity generates the instability, the weapons surplus, the ideological energy, and the operational cover that allow Pakistan’s anti-India outfits to train, recruit, and function with reduced scrutiny. The spillover is real. It simply does not flow in the straight line that headline writers prefer.

That distinction matters for the wider series. Across these pages, the safe haven has been mapped city by city, from Karachi’s anonymity to Rawalpindi’s garrison cover to the most lawless region where even the Pakistani military treads carefully. The Afghan frontier is the western wall of that structure. It is where the safe haven stops being a Pakistani phenomenon and becomes a regional one. It is also where the analytical questions get hardest, because attribution blurs, sovereignty arguments multiply, and the same patch of ground can be claimed as a victim of terrorism and an exporter of it within the same news cycle. The sections that follow take the frontier on its own terms: its geography, the organizations that hold it, the individuals who passed through it, the one elimination that touched it directly, the machinery of shelter it sustains, and the way the entire dynamic has been transformed since the Taliban returned to power.

Geography and Strategic Position

The boundary at issue was drawn in 1893 by Sir Mortimer Durand, foreign secretary of British India, in an agreement with the Afghan ruler Abdur Rahman Khan. It stretches for approximately 2,640 kilometers, although different sources cite figures between 2,400 and 2,670 depending on how the surveyors treated contested segments. From its northern anchor near the Pamir knot, where Afghanistan, Pakistan, and the narrow Wakhan Corridor converge, the line runs south and then southwest through the Hindu Kush, drops through the Spin Ghar range that Afghans call the White Mountains, threads the Khyber Pass, crosses the tribal districts, and finally descends into the deserts of Balochistan before terminating near the Iranian frontier. No segment of this line has ever been accepted by any Afghan government, Taliban or otherwise. Kabul’s consistent position, maintained across monarchy, republic, communist rule, and Islamic emirate, is that the Durand Line is a colonial imposition that bisected the Pashtun nation without consent and therefore lacks legitimacy. Islamabad regards the line as a settled international border. This is not a technical dispute. It is the foundational disagreement from which every cross-border security problem ultimately descends.

The terrain does the rest of the work. The Pashtun belt straddles the line, which means the same ethnic group, often the same tribe and sometimes the same extended family, lives on both sides. A Mohmand or an Afridi or a Wazir crossing the mountains is not entering foreign territory in any meaningful social sense. He is moving within his own homeland, along trails his ancestors used before any surveyor arrived. The mountains themselves are a smuggler’s paradise: thousands of unmarked footpaths, seasonal passes that open and close with the snow, gorges where a fence is physically impossible to anchor, and ridgelines where surveillance equipment loses line of sight. The handful of formal crossings concentrate the legal traffic and leave the rest of the frontier to informal movement. Torkham, on the Khyber route between Nangarhar and Pakistan’s tribal belt, is the busiest. Chaman, paired with the Afghan town of Spin Boldak, links Kandahar to Balochistan. Ghulam Khan connects North Waziristan to Khost. Kharlachi serves the Kurram district. These chokepoints handle the trucks, the trade, and the documented travelers. Everything and everyone else moves through the gaps.

Pakistan’s response to that porousness has been one of the most ambitious border-engineering projects in modern South Asian history. Beginning in 2017, the Pakistani military undertook the construction of a fence along nearly the entire Durand Line, a double-layered barrier of concertina wire and steel pickets, studded with watchtowers, forts, and surveillance cameras. By the early 2020s, Pakistani officials claimed the fence was more than ninety percent complete, describing it as a definitive answer to infiltration. The Taliban, after returning to power in August 2021, openly objected to the barrier and in several documented incidents Taliban fighters were filmed uprooting fence sections, an act that captured the unresolved sovereignty quarrel in physical form. The fence has unquestionably raised the cost of casual crossing. It has not closed the frontier. Militants adapted with the predictability that always follows fortification: they shifted to the high passes above the practical limit of fencing, they exploited the river valleys where the barrier cannot run, they bribed or coerced their way through gaps, and they used the formal crossings with forged or genuine documents. A wall is only as strong as the governance behind it, and the governance behind this wall remains thin on both sides.

Strategically, the frontier divides into three broad sectors, each with a distinct character. The northern sector, running from the Wakhan area down through Bajaur and the Mohmand district, faces the Afghan provinces of Kunar and Nangarhar. This is high, forested, and historically the most permeable stretch for fighters moving toward Kashmir, because it offers the shortest mountain routes and the densest canopy cover. The central sector covers the Waziristans, North and South, opposite the Afghan provinces of Khost, Paktia, and Paktika. This is the classic militant heartland, the zone where al-Qaeda regrouped after 2001 and where the Haqqani network built its dual-use empire. The southern sector runs through Balochistan opposite Kandahar and Helmand, the Taliban’s own birthplace and spiritual core, and the area where Baloch separatist insurgency overlaps with jihadist infrastructure. The shadow war’s deepest known penetration touched the central sector, when a Masood Azhar associate was shot in North Waziristan, an event examined in the profile of the JeM associate killed there. The frontier’s relevance to India scales differently across these three sectors, and any serious threat assessment has to disaggregate them rather than treat the border as a single undifferentiated danger.

Each of the provinces on the western side of the line carries its own security signature, and a planner who treats them as interchangeable misreads the frontier badly. Nangarhar, with its capital at Jalalabad and its position astride the Khyber route, has long been the most contested eastern province, a stronghold first of anti-Soviet commanders, then of insurgent networks, and after 2015 of the Islamic State’s Khorasan branch, which made the province’s southern districts an early base. Kunar, smaller and more vertical, is a maze of forested valleys that has defied every army that entered it, from the Soviets to the Americans, and it is the province where the contested death of the Kashmiri Islamic State recruit later occurred. Khost, Paktia, and Paktika, the cluster known historically as Loya Paktia, form the Haqqani network’s home ground, a zone of seminaries, cross-border clans, and the tunnels and compounds from which the network ran its war for two decades. Further south, Kandahar is the Taliban’s spiritual capital, the city where the movement was born in 1994 and where its supreme leader is based, while Helmand’s irrigated belt is the agricultural and narcotics heartland that financed the insurgency through twenty years of war. Reading the frontier therefore means reading a chain of distinct provinces, each with a different dominant actor, a different terrain, and a different relationship to the militancy that crosses into Pakistan. The eastern provinces feed the Kashmir-facing routes and host the Islamic State problem, the central provinces are the Haqqani heartland, and the southern provinces tie the Taliban’s core to the Baloch insurgency next door. A single label for the whole frontier obscures all of this, and obscuring it is the first step toward misjudging where the danger to India actually originates.

There is a final geographic point that commentary routinely underplays. The frontier is not only a corridor for fighters; it is a corridor for people on a scale that dwarfs the militant traffic. Afghan refugees have moved across this boundary in waves since the Soviet invasion of 1979, and at various points more than three million Afghans have lived inside Pakistan, concentrated in Khyber Pakhtunkhwa and Balochistan. In 2025 alone, roughly 2.9 million people crossed back into Afghanistan, many of them under a Pakistani repatriation drive, including individuals born in Pakistan decades earlier who had built entire lives there. This demographic churn is the medium in which militant movement hides. A handful of fighters embedded in a flow of hundreds of thousands of ordinary families are nearly impossible to filter at a crossing. The refugee corridor and the militant corridor are the same physical space, and that overlap is one of the central reasons the frontier defeats every attempt to seal it. The relationship between the provincial context of Khyber Pakhtunkhwa and the Afghan provinces across the line is not a border relationship in the ordinary sense. It is the relationship between two halves of one continuous, contested, and chronically unstable space.

Terror Organizations Present

The Afghan side of the frontier hosts a denser concentration of armed groups than almost any comparable territory on earth, and the first task in understanding the spillover is to separate these groups by their actual targets, because lumping them together produces exactly the analytical confusion this article exists to dispel. Five formations matter most: the Afghan Taliban itself, now the governing authority; the Haqqani network, folded into that government but retaining a distinct identity and history; the Tehreek-e-Taliban Pakistan, the anti-Pakistan insurgency; the Islamic State’s Khorasan Province, the anti-everything spoiler; and the residual presence of al-Qaeda. Around these orbit smaller entities, including Baloch separatist groups that Pakistan classifies as terrorists, and the thin, intermittent footprint of the Kashmir-focused outfits that are this series’ central subject.

Afghanistan’s Taliban returned to power in Kabul in August 2021 after a twenty-year insurgency against the United States and the Western-backed republic. Pakistan’s intelligence establishment, the Inter-Services Intelligence directorate, had been the Taliban’s principal external sponsor since the movement’s emergence in the mid-1990s, and Islamabad was one of only three governments to recognize the first Taliban emirate. That history produced a widely shared expectation that a Taliban-ruled Afghanistan would deliver Pakistan the prize its strategists had pursued for decades: strategic depth, a friendly western flank, and a partner in managing the frontier. The expectation has been almost completely inverted. The relationship between Islamabad and the Taliban government has deteriorated to the worst point since 2021, and the reason is the very ecosystem the frontier sustains. The Taliban’s victory did not give Pakistan a client. It gave the entire regional jihadist movement a demonstration that a patient insurgency can outlast a superpower and seize a state. That demonstration effect is itself a form of spillover, and its first and most damaging beneficiary has been the group that targets Pakistan rather than India.

The Tehreek-e-Taliban Pakistan, commonly shortened to the TTP and often called the Pakistani Taliban, was formed in 2007 as an umbrella for militants waging war against the Pakistani state. It is a separate organization from the Afghan Taliban, with a separate leadership and a separate objective, namely the overthrow of the Pakistani government and the establishment of its own emirate on the Afghan model. The two movements nonetheless share ideology, ethnic composition, culture, and a long history of mutual shelter. After August 2021, the TTP’s fortunes transformed. Pakistan’s own interior ministry told the federal parliament in December 2024 that the Afghan Taliban’s victory had emboldened TTP militants to operate without fear, and that the group’s central leadership had relocated to Afghan soil. The numbers attached to this resurgence are stark. More than 3,500 Pakistani security personnel and civilians have been killed in TTP attacks since 2021. Independent conflict monitors recorded over a thousand violent incidents involving the group across Pakistan in 2025, making that year one of the most violent in more than a decade. Pakistan’s army chief has claimed publicly that roughly seventy percent of the TTP fighters infiltrating into Pakistan are Afghan nationals. The emir of the TTP, Noor Wali Mehsud, survived a Pakistani airstrike that targeted him in Kabul in October 2025, an episode that confirmed both his presence in the Afghan capital and Islamabad’s willingness to strike there.

Sirajuddin Haqqani’s network occupies a category of its own, and it is the formation that should most concern Indian threat assessment. Founded by Jalaluddin Haqqani during the anti-Soviet jihad and later led by his son Sirajuddin Haqqani, the network operated for two decades as the most lethal and most professionalized component of the Afghan insurgency, specializing in complex urban attacks, suicide bombings, and high-value kidnappings. It maintained an unusually close relationship with Pakistan’s intelligence services while also retaining operational autonomy. With the Taliban’s return, Sirajuddin Haqqani became Afghanistan’s acting interior minister, placing the network’s leadership at the center of the Afghan state. The Indian relevance is direct and historical. The Haqqani network has been credibly linked to the suicide bombing of the Indian embassy in Kabul in 2008, an attack that killed dozens, including senior Indian diplomatic and military personnel, and Indian and American investigators tied that operation to Pakistani intelligence facilitation. The Haqqanis were also implicated in the 2009 attack on the embassy and in the 2014 assault on the Indian consulate in Herat. When Indian intelligence argues that Taliban-ruled Afghanistan poses a direct threat, the Haqqani network is the specific evidence it points to, because here is a formation with a documented record of killing Indians, a documented relationship with the intelligence apparatus that built the anti-India outfits, and a current seat in the cabinet.

The Islamic State’s Khorasan Province, usually abbreviated to ISKP or ISIS-K, formed in 2015 from defectors and rejectionists who found even the Taliban insufficiently extreme. It is anti-Taliban, virulently anti-Shia, and hostile to Pakistan and India alike. The group claimed the catastrophic bombing at Kabul airport during the 2021 evacuation and has carried out repeated mass-casualty attacks on Afghan Shia mosques, on the Russian embassy in Kabul, and on targets across the region. ISKP matters to the frontier story in a counterintuitive way. The Afghan Taliban actively suppresses it, particularly in the eastern provinces of Nangarhar and Kunar, and that suppression campaign is part of why those provinces are a kill zone for accused ISKP figures. ISKP also functions as a pressure valve and a recruiting rival: analysts note that the Afghan Taliban is reluctant to crack down too hard on the TTP partly because TTP fighters denied a home with the Taliban might defect to ISKP instead. For India, ISKP represents a low-probability but high-consequence threat, an organization that has tried, with very limited success, to recruit in Kashmir, a story examined through the figure of the Kashmiri ISIS recruit killed in Afghanistan.

A further set of actors orbits the major formations and deserves explicit treatment, because Pakistan has placed them at the center of its frontier narrative. Baloch separatist groups, principally the Balochistan Liberation Army, wage an ethno-nationalist insurgency against the Pakistani state in the southwestern province of Balochistan, and their grievance is secular and territorial rather than religious. They are not jihadist organizations, and they have no quarrel with India. Islamabad nonetheless classifies them as terrorists and, since the collapse of its relationship with the Taliban government, has accused them of operating from sanctuaries on the western side of the line with Indian backing. The Baloch insurgency matters to this analysis for two reasons. First, it illustrates how the frontier hosts multiple, ideologically incompatible armed movements that share only the common resource of ungoverned space, which means the spillover is not a single jihadist phenomenon but a crowded ecosystem of distinct insurgencies. Second, the Baloch case is the clearest example of Pakistan’s tendency to fold every security failure into a narrative of Indian sponsorship, a tendency examined later in this analysis. The separatists themselves reject both the jihadist label and the claim of foreign control, presenting their war as an indigenous response to decades of provincial marginalization. For the purposes of the shadow war this series documents, the Baloch groups are a reminder that the frontier’s instability has many engines, and that conflating them produces exactly the analytical confusion that careful work must resist.

Al-Qaeda’s presence is reduced but not erased, and one event settles the question of whether the organization retains shelter in Afghanistan. In July 2022, a United States drone strike killed Ayman al-Zawahiri, the leader of al-Qaeda and the man who succeeded Osama bin Laden, on the balcony of a house in central Kabul. The house was reportedly connected to the Haqqani network. Zawahiri was not hiding in a remote cave; he was living in a comfortable neighborhood of the Afghan capital, under the de facto protection of figures now in government. That single fact demolishes any claim that the new Afghanistan is closed to transnational jihadist leadership. Al-Qaeda’s operational capacity is a shadow of its early-2000s peak, but its ideological authority and its mentoring role within the broader movement persist, and the Kashmir-focused groups trace significant portions of their doctrine and their founding cohorts to the al-Qaeda-adjacent milieu of the Afghan jihad.

The wider constellation around al-Qaeda also includes a category that counterterrorism officials watch closely: the regional affiliates and the small cells of foreign fighters who never left the frontier after the campaigns of the 2000s. Al-Qaeda in the Indian Subcontinent, announced in 2014 as a dedicated South Asian branch, was conceived precisely to extend the organization’s reach into India, Bangladesh, and Myanmar. Its operational record has been modest, and Indian agencies have disrupted several of its attempted cells, but its very existence confirms that the transnational jihadist movement retains an explicit, stated intention to operate against India even where it lacks the capacity to do so at scale. Uzbek, Uighur, and other Central Asian militants displaced by conflict in their home regions have likewise sheltered along the frontier for years, lending the ecosystem a genuinely international character. None of these elements amounts to an organized campaign against India launched from the country next door. Together, however, they reinforce the article’s central point. The frontier is not dangerous because a single enemy headquarters sits there. It is dangerous because it is a reservoir, a place where ideology, expertise, weapons, and stated intent pool and mix, and where any of those ingredients can be drawn off by any group that wants them. A reservoir does not need to aim at a target to be a threat. It only needs to keep filling.

This brings the analysis to the groups that are this series’ actual subject. Lashkar-e-Taiba and Jaish-e-Mohammed are Pakistan-based, Pakistan-headquartered, and Pakistan-protected organizations. Their command centers sit in Punjab, at Muridke and Bahawalpur, not in Afghanistan. They do not run their India operations out of Kandahar. Anyone expecting to find a JeM headquarters in Khost will be disappointed, and the deep research behind the definitive guide to Jaish-e-Mohammed places the organization’s center of gravity firmly in Pakistani Punjab. The Afghan connection for these outfits is therefore not a matter of current basing. It is a matter of origin, ecosystem, and intermittent use. Their founders fought the Afghan jihad. Their ideological vocabulary was forged there. Their fighters have at times used Afghan territory for training or transit when Pakistani heat rose. And the broader instability that the Afghan frontier radiates outward gives them cover, weapons, and recruits. That is the indirect mechanism this article is built to explain, and it is far more important than the absent direct mechanism that careless commentary keeps searching for.

Terrorists Who Lived Here

The Afghan side of the frontier has functioned as a finishing school for South Asian jihad for more than four decades, and the careers of the individuals who passed through it reveal the spillover mechanism more clearly than any abstract diagram. The starting point is the anti-Soviet war of the 1980s. When the Soviet Union invaded Afghanistan in 1979, the resulting jihad drew fighters, money, and weapons from across the Muslim world, channeled overwhelmingly through Pakistan and its intelligence service. The training camps, the ideological seminaries, and the command relationships built during that decade did not dissolve when the Soviets withdrew in 1989. They were repurposed. The same infrastructure that produced anti-Soviet mujahideen was turned, in the early 1990s, toward Kashmir. This is not a contested claim; it is the documented origin story of the modern Kashmir insurgency, and it means that the founding generation of every major anti-India outfit has Afghan dust on its boots.

The crucible itself deserves description, because the term Afghan jihad is often used as a vague shorthand for a process that was in fact specific, organized, and consequential. Through the 1980s, Pakistan’s intelligence service operated a vast pipeline that received money from the United States and Saudi Arabia, purchased weapons, and channeled both to a set of favored mujahideen factions fighting the Soviet occupation. Alongside that state pipeline ran a parallel, semi-private network that recruited volunteers from across the Arab world and beyond, men drawn by the call to defend Muslim land, who arrived in the frontier city of Peshawar, passed through guesthouses and training camps, and crossed the mountains to fight. It was within this milieu that Osama bin Laden built the organization that would become al-Qaeda, and it was here that the doctrines, the camp curricula, and the personal bonds of a generation of militants were formed. When the Soviets withdrew and the government they left behind eventually fell, this enormous apparatus of camps, trainers, financiers, and ideologues did not evaporate. It was idle, experienced, and available. Pakistan’s strategic planners, already contemplating a low-cost way to pressure India in Kashmir, found in this apparatus a ready-made instrument. The pivot from the anti-Soviet war to the Kashmir insurgency was therefore not improvised. It was the redirection of a machine that already existed, staffed by men who already knew one another, using methods already refined over a decade of combat. That continuity is the deepest root of the spillover, and it explains why the frontier cannot be separated from the story of anti-India terrorism even now, decades later.

Consider the lineage. Hafiz Saeed and Zafar Iqbal founded Lashkar-e-Taiba’s parent body in the late 1980s in the context of the Afghan jihad, and the organization’s early operational cadre cut its teeth in the anti-Soviet campaign before pivoting to Kashmir, a trajectory traced in the definitive guide to Lashkar-e-Taiba. Masood Azhar, who would later found Jaish-e-Mohammed, spent his formative years in the Afghan-jihad milieu, traveled to Somalia and elsewhere as an itinerant ideologue of armed jihad, and built JeM in 2000 on a network of contacts and camps that reached across the Afghan frontier. The very weapons, tactics, and training doctrines that LeT and JeM brought to Kashmir were Afghan inheritances. When the analysis speaks of an ecosystem, this is the concrete content of the word: a transferable body of skills, relationships, and infrastructure that was created in Afghanistan, matured across the frontier, and is now aimed at India. The men eliminated in the shadow war’s Pakistani phase are the grandchildren, ideologically speaking, of the Afghan jihad’s founding cohort.

The single most analytically important individual for this frontier story is Aijaz Ahmad Ahangar. Unlike the LeT and JeM figures who trained near Afghanistan but operated from Pakistan, Ahangar’s life ran the other way. He was a Kashmiri, born in Srinagar, who left Indian-administered Kashmir, spent years in the militant networks of the frontier, and ultimately attached himself to the Islamic State’s Khorasan operation in Afghanistan. He became, by Indian intelligence assessments, one of the most senior South Asians in the ISKP structure and a recruiter who tried to draw Kashmiri youth toward the Islamic State’s banner. His value to this analysis is precisely that he is the exception that proves the rule. ISKP’s effort to recruit in Kashmir, an effort in which Ahangar was central, almost entirely failed. The Islamic State never established a meaningful Kashmir franchise, and the handful of young men who flirted with its propaganda did not translate into an operational network. Ahangar’s career is the clearest available test case for whether Afghan soil functions as a launchpad for India-focused terrorism, and the verdict that test returns is largely negative. The full arc of his radicalization and his connection to the Islamic State is examined in the dedicated profile of the Kashmiri ISIS recruit found dead in Kunar.

Then there is the leadership tier that physically resides on the Afghan side. Sirajuddin Haqqani, acting interior minister of Afghanistan, lives and governs from Kabul. Noor Wali Mehsud, emir of the TTP, was confirmed present in Kabul when a Pakistani airstrike targeted him there in October 2025. Ayman al-Zawahiri lived openly enough in a Kabul neighborhood that an American drone found him on a balcony in July 2022. These are not transients passing through a corridor. They are men who chose Afghanistan as a place of residence because the Afghan state, as currently constituted, offers them shelter that no other country would. The contrast with the anti-India outfits is instructive and should be stated plainly. The senior leadership of Lashkar-e-Taiba and Jaish-e-Mohammed does not live in Kabul. Hafiz Saeed has spent years in and out of detention in Pakistani Punjab. Masood Azhar’s whereabouts have been the subject of intense speculation, but the consistent assessment places him in Pakistan, not Afghanistan. The geography of residence tells the truth that the geography of rhetoric obscures: the men who target Pakistan and the men who target the West increasingly shelter in Afghanistan, while the men who target India shelter in Pakistan. The Afghan frontier feeds the India threat indirectly, through the ecosystem, not directly, through basing.

A final category deserves mention because it complicates the clean picture. The Afghan jihad and the subsequent decades of frontier warfare produced a floating population of fighters who do not belong neatly to any single organization. They are veterans, facilitators, fixers, and ideologues who move between groups, lend their skills to whoever is paying, and carry the institutional memory of four decades of conflict. Some of these men have, at various points, supported Kashmir-focused operations. Lashkar-e-Jabbar, the obscure JeM affiliate to which the North Waziristan victim was tied, is exactly the kind of peripheral, frontier-zone outfit that this floating population sustains. These figures are nearly impossible to track, because they have no fixed organizational address, and they are one reason the frontier remains dangerous even when the major groups can be located precisely. The shadow war has demonstrated that it can reach named individuals in known Pakistani cities. The floating frontier population is a harder problem, and Afghanistan is where much of it resides.

Eliminations in This Location

An honest answer to the question of how many shadow-war eliminations have occurred on Afghan soil is: very few, possibly only one, and even that one is contested. This section does not pad a thin record into a false pattern. It examines the single relevant case rigorously, places it against a genuine point of comparison, and draws the correct conclusion about the limits of the campaign’s reach.

The case is the death of Aijaz Ahmad Ahangar. In February 2023, Ahangar was found dead in Kunar Province, in eastern Afghanistan, a mountainous region bordering Pakistan’s Bajaur district. The circumstances were never clarified to anyone’s satisfaction. Reporting indicated he had been killed, but the identity of the killers, the method, and the motive all remained obscure. Two explanations compete, and intellectual honesty requires giving both their full weight rather than forcing the case into the shadow-war narrative.

One explanation attributes the killing to the India-linked targeted-killing campaign. Under this reading, Ahangar fits the established victim profile: a designated terrorist with a documented anti-India record, eliminated by unidentified assailants in circumstances that the relevant state never investigated transparently. If the campaign that has reached Karachi, Lahore, Rawalpindi, and Pakistan-administered Kashmir also reached Kunar, then Ahangar’s death would represent the deepest geographic extension of the entire effort, proof that no terrain is beyond the campaign’s range. The second explanation attributes the killing to the Afghan Taliban’s own suppression of the Islamic State. Kunar and the neighboring province of Nangarhar are precisely the zone where the Taliban has waged its most sustained campaign against ISKP, and the Taliban has killed, captured, and disappeared numerous accused Islamic State operatives there as part of consolidating its rule. Ahangar, as a senior ISKP figure, was a natural target for that internal purge. The Taliban had every motive to kill him, the means to do so, and the territorial control to act without explanation.

The evidence does not decisively favor either reading, and this analysis declines to manufacture a certainty the facts cannot support. What can be said is that the Taliban-suppression explanation is at least as plausible as the campaign explanation, and arguably more so, because it requires fewer assumptions. The campaign explanation requires the India-linked effort to have developed assets capable of operating in one of the most hostile environments on earth, a Taliban-controlled province where outsiders are immediately conspicuous and the governing authority is itself hunting the same category of target. The suppression explanation requires only that the Taliban did what the Taliban demonstrably does. Ahangar’s case is therefore the weakest attribution in the entire shadow-war record, and treating it as a confirmed campaign success would be a failure of analytical discipline. The most defensible conclusion is that the frontier has seen one death of a relevant figure, that the death may or may not connect to the campaign, and that the uncertainty itself is the finding.

A genuine point of comparison sharpens the lesson. In July 2022, a confirmed and acknowledged targeted killing did occur on Afghan soil: the United States drone strike that killed Ayman al-Zawahiri in Kabul. That operation succeeded because it was backed by the intelligence, surveillance, and standoff strike capability of a superpower, and even then it required years of patient tracking and a precise window. It involved no asset on the ground in the moment of the strike, because the kill was delivered from the air. The contrast with the shadow war’s signature method is total. The eliminations in Pakistani cities have been close-range shootings, typically by men on motorcycles, demanding human assets physically present at the target. That method, examined across many profiles including the JeM associate killed in North Waziristan, depends on a permissive enough environment for an assassin to approach, fire, and escape. Taliban-controlled Afghanistan is not such an environment. The Zawahiri precedent shows that killing on Afghan soil is possible, but only with capabilities the India-linked campaign has never demonstrated.

It is worth pausing on what the Ahangar case teaches about attribution itself, because the discipline required here applies across the entire shadow war. A killing becomes evidence of a covert campaign only when several conditions converge: a victim who fits the established target profile, a method consistent with the campaign’s known signature, a location within the campaign’s demonstrated operational reach, and an absence of equally strong competing explanations. The eliminations in Pakistani cities satisfy most of these conditions, which is why they can be discussed as a pattern. The death in Kunar satisfies only the first. Its victim fit the profile, but the method was never established, the location lay far outside any demonstrated reach, and a powerful competing explanation, namely the Taliban’s own war on the Islamic State, was readily available. An analyst who counted Kunar as a campaign success would be privileging a preferred narrative over the evidentiary standard, and that is precisely the error this series exists to avoid. The honest treatment is to record the case as unresolved and to let the uncertainty stand as a finding in its own right. Doing so is not a weakness of the analysis. It is the analysis working correctly, because a framework that can absorb any death into its preferred story is a framework that explains nothing. The frontier, in this sense, marks the outer edge not only of the campaign’s reach but of what can be responsibly claimed about it.

The correct takeaway is not that the frontier is irrelevant to the shadow war. It is that the frontier’s relevance is structural rather than operational. The campaign has not turned Afghanistan into a kill zone, and the evidence gives no reason to expect it to. What Afghanistan does is feed the ecosystem that produces the targets the campaign eliminates elsewhere. The eliminations happen in Pakistan. The conditions that create the men who get eliminated are manufactured, in significant part, across the line. That is why a series mapping the safe haven city by city cannot skip the country next door, even though the country next door contributes almost nothing to the body count and almost everything to the supply.

The Infrastructure of Shelter

How Afghan instability sustains anti-India terrorism can be set out precisely, and doing so is the analytical core of this article. The spillover is not a single pipe carrying a single substance. It is a set of distinct flows, each moving a different commodity in a different direction, and together they constitute the bloodstream that keeps the jihadist ecosystem alive. Five flows matter: instability itself, personnel, weapons, ideology, and money. Tracing each one shows how a problem that looks like Pakistan’s internal headache becomes, by extension, a problem for Indian security.

The first flow is instability, and it moves outward from Afghanistan in every direction. A state that cannot govern its own territory, that is at war with an insurgency on its soil, and that is locked in escalating conflict with its eastern neighbor generates a permanent field of disorder. That disorder is itself the resource. It absorbs the attention and the security bandwidth of the Pakistani state, which must devote troops, intelligence, and political capital to the western frontier rather than to dismantling the anti-India outfits in Punjab. Every Pakistani soldier deployed against the TTP in Bajaur is a soldier not deployed to constrain Lashkar-e-Taiba in Muridke. The cross-border war that erupted in full force in early 2026, with Pakistani airstrikes deep into Afghan provinces and Afghan retaliation along the Durand Line, consumed the Pakistani security establishment for months. The anti-India groups are among the quiet beneficiaries of that distraction. Instability does not have to be aimed at India to help India’s enemies; it simply has to exist, and Afghanistan manufactures it in surplus.

A second flow carries personnel, and it runs in both directions across the line. Fighters move from Afghanistan into Pakistan to wage the TTP’s war, and Pakistan’s own army chief has stated that roughly seventy percent of the TTP formations infiltrating Pakistan are composed of Afghan nationals. Fighters and refugees move from Pakistan into Afghanistan, including the 2.9 million people who crossed westward in 2025. Within this churn, the militant networks recruit, rotate, and reconstitute. The personnel flow matters for India in two ways. First, it keeps the broader fighting population large, experienced, and circulating, which is the labor pool from which all the region’s jihadist outfits, including the Kashmir-focused ones, ultimately draw. Second, it normalizes cross-border militant movement to a degree that makes any specific transit, including transit by an anti-India operative, harder to detect. When hundreds of thousands of people and thousands of fighters are in motion, the frontier’s monitoring capacity is saturated. A flow that large cannot be filtered finely enough to catch the specific individuals who matter most.

The third flow is weapons, and it is the most concrete and the most alarming. When the United States and its NATO partners withdrew from Afghanistan in 2021, they left behind an enormous quantity of modern military equipment that had been supplied to the collapsed Afghan republic’s army: assault rifles, machine guns, night-vision devices, optics, communications gear, and more. A significant portion of that arsenal passed into the hands of the Taliban and, from there, leaked into the wider militant marketplace. Pakistani security officials have directly attributed the increased lethality of TTP attacks to the militants’ acquisition of this advanced American weaponry. A frontier that was already one of the world’s densest informal arms markets received a sudden, massive injection of high-quality matériel. Weapons do not respect the distinction between anti-Pakistan and anti-India militancy. A night-vision device or a modern carbine that enters the ecosystem through the Afghan stockpile can end up in the hands of any group operating in the region. The weapons flow is the clearest case of Afghan instability directly upgrading the capabilities of the entire jihadist environment, and the upgrade is permanent, because the equipment is now in circulation and cannot be recalled.

Ideology forms the fourth flow, and it is the least tangible but arguably the most consequential. The Taliban’s victory in August 2021 was not merely a change of government in one country. It was, for the global jihadist movement, a proof of concept. A religiously motivated insurgency had fought the world’s most powerful military for twenty years and won, outlasting the occupier and seizing the state. That narrative is intoxicating, and it propagates outward without needing any physical corridor at all. Pakistan’s own interior ministry acknowledged in writing that the Taliban victory emboldened the TTP. The same emboldening effect reaches every group in the region that shares the underlying ideology, and the Kashmir-focused outfits share it. The ideological flow tells young men across South Asia that armed jihad can deliver victory, that patience pays, and that the apparent strength of a state is an illusion that determination can dissolve. No fence stops an idea. The Afghan example refreshes the ideological energy of the entire movement, and that refreshment is a direct input into the recruitment pitch of organizations that target India.

The fifth flow is money, and it moves through the same informal channels that have always defied the frontier. The border economy runs on smuggling, on the unrecorded movement of goods through the high passes and around the formal crossings, and on the hawala system of trust-based, paperless value transfer. Trade and transit through Torkham and Chaman are large enough that their disruption during the 2025 and 2026 closures cut measured bilateral trade from roughly 2.46 billion dollars in 2024 to about 1.77 billion in 2025, and the informal economy that operates alongside the official one is larger still. Militant financing rides these channels. Funds raised through charity fronts, criminal activity, and external donors can be moved across the region without touching a regulated bank, and the frontier’s smuggling infrastructure provides the physical and financial plumbing. The money flow sustains the camps, the salaries, the safe houses, and the families of fighters, and it does so for the whole ecosystem, the anti-India component included.

Underlying all five flows is an institution that deserves separate mention, because it is the quiet engine that keeps the others supplied: the seminary belt that runs along both sides of the frontier. For decades, a dense network of religious schools, many of them teaching a hardline interpretation of the Deobandi tradition, has lined the border districts of Khyber Pakhtunkhwa and Balochistan and extended into the provinces beyond. Most of these schools are ordinary places of religious instruction with no connection to violence. A consequential minority, however, have functioned as recruitment funnels and ideological factories, taking in boys from impoverished families, providing them with food, shelter, and an education that the state failed to deliver, and exposing some of them to a worldview in which armed jihad is a religious obligation. The Taliban movement itself emerged in the early 1990s substantially from this seminary network, and the very name of the movement means students. The same institutional ecosystem that produced the Taliban has, over the years, fed fighters into the TTP, into the Kashmir-focused outfits, and into the wider movement. Because these schools sit outside or at the margins of state regulation, and because shutting them would require confronting powerful religious constituencies, successive Pakistani governments have left the network largely intact. The seminary belt is therefore the human renewal mechanism of the entire frontier ecosystem. The weapons flow can be interdicted in principle, and the money flow can be traced in principle, but the steady production of indoctrinated young men continues year after year, and it is the hardest input of all to switch off.

These five flows do not operate in isolation. They reinforce one another. Instability creates the cover under which personnel move. Moving personnel carry weapons and ideology. Weapons and ideology raise the value and the reach of the networks, which generates more money, which funds more recruitment, which feeds back into instability. The result is a self-sustaining circuit, and the circuit’s western node is the Afghan frontier. The infrastructure of shelter, in the Afghan case, is not a set of buildings. It is this circulatory system. The madrassas of the border belt, the seminaries that have radicalized generations of frontier youth, the smuggling depots, and the refugee settlements are the organs through which the flows pass, but the shelter itself is the system’s continued operation. The terror training camps mapped across Pakistan and the Quetta and Balochistan nexus are the eastern and southern extensions of a single regional structure whose deepest roots run into Afghan ground. Understanding the spillover means understanding that the safe haven is not a Pakistani building. It is a regional bloodstream, and Afghanistan is part of the heart.

How the Shadow War Changed This Region

The Afghan frontier in 2026 is a fundamentally different strategic environment than it was a decade earlier, and the transformation is best understood as a sequence of reversals, each of which upended an assumption that had governed regional policy for years.

A first and largest reversal concerns Pakistan itself. For a generation, the Pakistani security establishment pursued a single overriding objective in Afghanistan, the achievement of what its strategists called strategic depth. The concept held that a friendly, pliable Afghanistan would give Pakistan a secure western flank, a fallback in any war with India, and a theater in which to host and train the militant proxies it directed eastward. The Inter-Services Intelligence directorate invested four decades and immense resources in this project, sponsoring the Afghan Taliban from the movement’s birth and recognizing its first emirate in the 1990s. When the Taliban swept back into Kabul in August 2021, Pakistani commentators openly celebrated, treating the moment as the culmination of the strategic-depth dream. The years since have delivered the opposite. Instead of a client, Pakistan acquired a neighbor that shelters the insurgency tearing at Pakistan’s own frontier provinces. Instead of strategic depth, Pakistan got strategic strain. By late 2025 and into 2026, the relationship had collapsed into open conflict, with Pakistani airstrikes reaching Kabul, Kandahar, and a string of eastern provinces, and Afghan forces striking back along the Durand Line. A Pakistani defense minister publicly described the two countries as being in a state of open war. The project that was supposed to secure Pakistan’s western flank instead opened a second front, and the militant ecosystem the project nurtured now bites the hand that built it.

The second reversal concerns the TTP and the geometry of the safe haven. For years, the conventional account ran in one direction: militants used Afghanistan as a rear base and Pakistan as the theater of operations. After 2021 that geometry inverted for the anti-Pakistan insurgency. The TTP’s central leadership relocated onto Afghan soil, Afghanistan became, in the words of Pakistani officials, one large sanctuary for the group, and the cross-border raids now flow eastward from Afghan bases into Pakistani territory. The TTP killed more than 3,500 Pakistani security personnel and civilians between 2021 and the end of 2025, and 2025 ranked among the most violent years in over a decade, with conflict monitors logging more than a thousand TTP-linked incidents. Pakistan’s response, a series of cross-border airstrikes code-named at various points Khyber Storm and later folded into a broader campaign, marked an open admission that the safe haven it had spent decades cultivating had escaped its control. The shadow war this series documents is India’s covert campaign against anti-India terrorists. What the Afghan frontier shows is a parallel and far bloodier conflict, Pakistan’s overt war against the anti-Pakistan terrorists its own ecosystem produced. The two campaigns are not the same, but they share a root, and that shared root is the regional jihadist infrastructure that the Pakistan terror safe haven network and the Afghan sanctuary jointly constitute.

India is the subject of the third reversal, and it is the one most relevant to this series. For two decades, India was a committed partner of the anti-Taliban order. New Delhi had backed the Northern Alliance against the first Taliban emirate in the 1990s, and after the 2001 American invasion India became one of the largest development donors to the Western-backed republic, building roads, a parliament building, dams, and clinics. The Taliban and its allies treated India as an enemy accordingly, and the Haqqani network’s strikes on the Indian embassy in Kabul in 2008 and 2009 and on the Herat consulate in 2014 were the violent expression of that hostility. When the republic collapsed in 2021, India closed its embassy and withdrew, and the assumption across South Asia was that a Taliban Afghanistan would be uniformly hostile to Indian interests. That assumption has not held. India reopened a small technical mission in Kabul in 2022 to manage humanitarian aid, and then, in a striking shift, the Afghan acting foreign minister Amir Khan Muttaqi traveled to New Delhi in October 2025, the most senior Taliban official to visit India since the movement’s return. During that visit India announced it would upgrade the technical mission to a full embassy, a step formalized on the twenty-first of October. By January 2026 a Taliban-appointed charge d’affaires was installed at the Afghan embassy in New Delhi. India has been careful not to extend formal recognition, and its calculus is explicitly strategic rather than warm: a diplomatic foothold in Kabul lets New Delhi monitor threats, counterbalance Chinese inroads, and exploit the very Pakistan-Taliban rift that the frontier conflict has produced.

This Indian rapprochement with the Taliban is the context in which the central analytical question of the article must finally be adjudicated. The named disagreement is whether Taliban-ruled Afghanistan poses a direct threat to India or only an indirect one. Indian intelligence has historically argued the direct case, and its argument is not frivolous. It points to the Haqqani network, a formation with a documented record of killing Indians, now seated in the Afghan cabinet through Sirajuddin Haqqani’s interior ministry. It points to the structural relationship between the Haqqanis and the Pakistani intelligence service that built Lashkar-e-Taiba and Jaish-e-Mohammed. And it warns that a hostile actor in Kabul could, if it chose, provide space for anti-India plotting. Against this, a number of Western analysts and a growing body of evidence support the indirect case. They observe that the Taliban government, whatever its ideological character, has shown no operational interest in attacking India, that Muttaqi during his Delhi visit explicitly stated Afghan territory would not be used to target other nations, and that the Taliban’s overwhelming security preoccupations are domestic, namely the war with ISKP and the deteriorating confrontation with Pakistan. They note that no India-focused terrorist attack in recent years has been credibly traced to planning on Afghan soil, and that ISKP’s effort to build a Kashmir franchise, the one genuine attempt to weaponize Afghan territory against India, comprehensively failed.

The evidence, weighed honestly, favors the indirect interpretation, with one important qualification. The direct-threat case rests heavily on the Haqqani network’s history and on a hypothetical, namely what a hostile Kabul could do if it decided to. The indirect-threat case rests on the observed behavior of the Taliban government across more than four years in power, and that behavior has not included sponsorship of anti-India terrorism. A government consumed by an existential war with Pakistan and a vicious internal struggle with the Islamic State has neither the bandwidth nor the incentive to open a third front against India, particularly while it is actively courting Indian investment and diplomatic engagement. The qualification is that the indirect threat is not a lesser threat; it is a different one, and in some respects a more intractable one. A direct threat can be deterred, sanctioned, and negotiated away, because it has a return address. The indirect threat has no return address. It is the cumulative output of an ecosystem, and an ecosystem cannot be summoned to a negotiating table. The weapons that leaked from the abandoned Afghan arsenals are in circulation permanently. The ideological charge of the Taliban’s victory cannot be revoked. The instability that absorbs Pakistan’s security bandwidth will persist as long as the Pakistan-Afghanistan conflict does. India faces, from the Afghan frontier, not a gun pointed at it but a furnace that keeps the region’s jihadist metal hot.

The frontier has also changed in a way that complicates Pakistan’s preferred narrative, and the change deserves explicit statement because it bears directly on the shadow war’s information environment. As the Pakistan-Taliban relationship collapsed, Islamabad began to allege that the Afghan Taliban and India were colluding to support the TTP and Baloch separatist groups against Pakistan. Pakistani military and civilian officials advanced this claim repeatedly through 2025, framing the militancy on the western frontier as an Indian-sponsored proxy war. India has denied the allegation, and no credible public evidence has substantiated it. The claim is best understood as a strategic narrative, the western-frontier analogue of the counter-narrative that Pakistan has deployed regarding the targeted killings on its own soil. For years Pakistan dismissed, minimized, and then reattributed the shadow war’s eliminations rather than confront what they revealed about the safe haven, a pattern of narrative management documented elsewhere in this series. The India-collusion charge on the Afghan frontier follows the same logic: when an uncomfortable security failure becomes undeniable, attribute it to the external enemy. The analytically serious point is that Pakistan’s frontier crisis is overwhelmingly a product of its own decades-long investment in jihadist proxies, an investment that has now slipped its leash. Blaming India is easier than acknowledging that the strategic-depth doctrine produced a strategic catastrophe.

Beyond Pakistan and India, the frontier’s transformation has also drawn in outside powers whose calculations now shape the regional picture in ways that bear on Indian security. China has emerged as the most consequential external actor in Taliban-ruled Afghanistan, pursuing access to mineral wealth, seeking to extend its Belt and Road investments, and pressing the Kabul government for guarantees against Uighur militants using the country as a base. Beijing’s deepening footprint is one of the explicit reasons New Delhi judged that diplomatic absence from Kabul had become a strategic liability. Iran, sharing a long western border, manages its own mix of concerns: the security of the Shia Hazara minority that the Islamic State targets, control of refugee flows, and water disputes along shared rivers. Russia, which formally removed the Taliban from its list of banned organizations and moved toward recognition, views the Islamic State’s Khorasan branch as the principal regional danger, particularly after that group’s reach extended to attacks on Russian soil. The Central Asian republics to the north watch the frontier nervously, fearing that instability and militant ideology will seep across their own borders. The cumulative effect is that the Afghanistan-Pakistan frontier is no longer a contained South Asian problem. It is a theater in which several major powers now hold stakes, and that internationalization cuts both ways for India. It raises the diplomatic cost of any single actor sponsoring cross-border terrorism, because more capitals are watching. It also makes the frontier more crowded, more contested, and harder to stabilize, because each external power pursues its own priorities and none has the leverage or the will to impose order on the whole.

One further change inside the country deserves attention, because it complicates any simple forecast. The Taliban government is not the monolith its enemies sometimes describe. A real fault line runs between the movement’s Kandahar-based supreme leadership, which sets ideological policy and has shown little interest in foreign entanglements, and the more pragmatic, internationally engaged figures around the Haqqani network and the foreign ministry, who favor cultivating relations with regional powers including India. On the question of the TTP, this divide has practical consequences. Some Taliban factions feel an ethnic and personal sympathy for the Pakistani militants who sheltered them through their own insurgency and are reluctant to move against them. Others recognize that the TTP’s war on Pakistan is dragging their own country into a ruinous cross-border conflict it can ill afford. The government has at times attempted to mediate between the TTP and Islamabad, and at other times has appeared unwilling or unable to constrain the group at all. For India, this internal complexity is double-edged. It means there is no single decision-maker in Kabul who can simply switch the frontier’s militancy on or off, which limits both the threat and the leverage. It also means that the more pragmatic, India-engaging faction is in a genuine contest with harder-line elements, and that the trajectory of the relationship will depend in part on which tendency prevails inside a government that is still, four years on, working out what kind of state it intends to be.

How, then, has the shadow war specifically changed this region? The honest answer is that the shadow war has changed the Afghan frontier far less than the Afghan frontier has shaped the shadow war. The campaign of targeted killings did not reach into Afghanistan in any sustained way, and the single contested case in Kunar does not establish a pattern. What changed is the strategic backdrop against which the campaign operates. The collapse of the Pakistan-Taliban relationship has tied down the Pakistani security establishment on its western flank, reducing the attention available to shield the anti-India outfits in Punjab. The India-Taliban rapprochement has given New Delhi a listening post in Kabul and a stake in the Pakistan-Taliban rift. The 2025 and 2026 cross-border war demonstrated that even a nuclear-armed state cannot wall off a hostile ecosystem next door. For the Kashmir-focused groups that this series tracks, the net effect of the frontier’s transformation is ambiguous. The instability gives them cover and keeps the weapons and recruits flowing. The same instability has made their Pakistani patrons weaker, more distracted, and more internationally exposed than at any point in two decades. The frontier did not become a theater of the shadow war. It became the unstable ground on which the entire structure of the safe haven now visibly trembles, and the geographic contraction of that structure is the subject the series turns to next as it examines how the safe-haven map is being redrawn under sustained pressure.

Frequently Asked Questions

Q: How does Afghanistan’s instability affect India’s security?

Afghan instability affects India through an indirect mechanism rather than a direct one, and grasping that distinction is the key to a sober threat assessment. There is no Taliban government plot to attack India, and no India-focused terrorist headquarters operates from Kabul or Kandahar. What Afghanistan provides is the unstable medium in which the entire regional jihadist movement renews itself. The disorder generated by a country at war with its own insurgency and with its eastern neighbor absorbs the security bandwidth of Pakistan, the state that actually shelters the anti-India outfits, leaving those outfits less constrained. The weapons that leaked from abandoned arsenals after the 2021 Western withdrawal upgraded the entire militant marketplace. The ideological charge of the Taliban’s victory refreshed the recruitment pitch of every jihadist group in the region, including the Kashmir-focused ones. The personnel churn across a frontier that also carries millions of refugees normalizes militant movement and saturates monitoring capacity. None of these flows is aimed specifically at India, yet each one strengthens the ecosystem from which India’s enemies draw. The practical consequence for Indian security planners is that the Afghan problem cannot be addressed through deterrence directed at Kabul, because Kabul is not the source of the threat in the conventional sense. The threat is the ecosystem itself, and an ecosystem does not respond to ultimatums.

Q: Does the Taliban government pose a direct threat to India?

On the available evidence, the Taliban government does not pose a direct threat to India, although the question is genuinely contested and the answer carries a real qualification. The case for a direct threat rests primarily on the Haqqani network, a formation with a documented history of killing Indians in Kabul and Herat and now seated in the Afghan cabinet through Sirajuddin Haqqani’s interior ministry. That history is real and should not be dismissed. The case against a direct threat rests on the observed behavior of the Taliban administration across more than four years in power, behavior that has not included sponsorship of anti-India operations. The movement’s security attention is consumed almost entirely by two other conflicts, the war against the Islamic State’s Khorasan branch and the escalating confrontation with Pakistan. During the Afghan foreign minister’s October 2025 visit to New Delhi, Kabul explicitly stated that Afghan soil would not be used to target other nations, and the broader trajectory has been one of cautious engagement, including the upgrading of India’s mission in Kabul to a full embassy. A government courting Indian investment while fighting an existential war on two other fronts has neither the incentive nor the capacity to open a third front. The qualification is that a hostile actor in Kabul could, in principle, change this calculus, which is why Indian intelligence remains watchful even as it engages.

Q: What is the Durand Line and why has no Afghan government accepted it?

The Durand Line is the boundary between Afghanistan and Pakistan, drawn in 1893 by Sir Mortimer Durand, the foreign secretary of British India, in an agreement with the Afghan ruler Abdur Rahman Khan. It runs for roughly 2,640 kilometers from the Pamir region in the north to the Iranian frontier in the southwest, threading the Hindu Kush, the Khyber Pass, the tribal districts, and the deserts of Balochistan. The reason no Afghan government has ever accepted it is that the line cut directly through the homeland of the Pashtun people, dividing a single ethnic nation between two states without the consent of the population it split. Every Afghan government across the past century, including the monarchy, the republics, the communist regime, and both Taliban emirates, has rejected the line’s legitimacy, regarding it as a colonial imposition. Pakistan, by contrast, treats the boundary as a settled international border and has invested heavily in fencing it. This is not an antiquarian quarrel. The sovereignty dispute is the foundational reason cross-border security cooperation has always failed: the two states cannot jointly police a line whose very existence one of them denies. When Taliban fighters were filmed uprooting sections of the Pakistani border fence after 2021, they were enacting that century-old rejection in physical form, and the dispute continues to poison every attempt at frontier management.

Q: Why can’t Pakistan’s border fence stop militant infiltration?

Pakistan began constructing a fence along nearly the entire Durand Line in 2017, a double-layered barrier of concertina wire and steel pickets reinforced with watchtowers and forts, and by the early 2020s officials claimed it was more than ninety percent complete. The fence has raised the cost of casual crossing, but it has not sealed the frontier, for reasons that are structural rather than technical. The terrain itself defeats fencing: thousands of unmarked footpaths, high mountain passes that open and close with the snow, gorges where a barrier cannot be physically anchored, and ridgelines where surveillance loses line of sight. Militants adapted to the fence with complete predictability, shifting to the high routes above the practical limit of construction, exploiting river valleys, bribing or coercing their way through gaps, and using the formal crossings with forged or genuine documents. The deeper problem is governance. A barrier is only as effective as the state capacity behind it, and on both sides of this line that capacity is thin. The Afghan side is governed by an administration that rejects the boundary outright and has been filmed dismantling the fence. The Pakistani side includes tribal districts where the writ of the state has always been contested. A fence cannot substitute for governance, and where governance is absent, a fence becomes an obstacle to be routed around rather than a wall that stops movement.

Q: What is the difference between the Afghan Taliban and the Pakistani Taliban?

Afghanistan’s Taliban and Pakistan’s Taliban share a name, an ideology, an ethnic base, and a long history of mutual support, but they are distinct organizations with opposite objectives, and confusing them produces serious analytical errors. The Afghan Taliban is the movement that emerged in the mid-1990s, ruled Afghanistan until 2001, waged a twenty-year insurgency against the United States and the Western-backed republic, and returned to power in Kabul in August 2021. It now governs Afghanistan and seeks normal, cooperative relations with neighboring states, including Pakistan. The Pakistani Taliban, formally the Tehreek-e-Taliban Pakistan and usually abbreviated TTP, was formed in 2007 as an umbrella for militants waging war against the Pakistani state, and its goal is the overthrow of the government in Islamabad and the establishment of its own emirate on the Afghan model. The two movements are bound by shared culture and by the fact that the TTP’s leadership and fighters have repeatedly taken shelter on Afghan soil, particularly after the Afghan Taliban’s 2021 victory. They have also experienced friction, because the Afghan Taliban’s interest in cooperation with Pakistan sits uneasily with the TTP’s war against Pakistan. The crucial point for this series is that neither organization targets India as a primary objective, which is why the Afghan frontier’s threat to Indian security is indirect.

Q: How did the Taliban’s 2021 victory embolden the TTP?

The Tehreek-e-Taliban Pakistan was a battered organization in the years before 2021, fractured by Pakistani military operations and leadership losses. The Afghan Taliban’s return to power transformed its situation, and Pakistan’s own interior ministry acknowledged the transformation in writing, telling the federal parliament in December 2024 that the Afghan Taliban’s victory had emboldened TTP militants to operate without fear and that the group’s central leadership had relocated onto Afghan soil. The emboldening worked through several channels at once. Ideologically, the Afghan victory proved that a patient religious insurgency could outlast a superpower and seize a state, an intoxicating demonstration for any group pursuing a similar goal. Practically, a sympathetic government in Kabul gave the TTP secure rear bases, room to reorganize, and a leadership sanctuary beyond the reach of routine Pakistani operations. Materially, the weapons that flooded the region after the Western withdrawal upgraded the group’s firepower, and Pakistani officials have directly linked the increased lethality of TTP attacks to the acquisition of advanced American equipment. The results were measurable. More than 3,500 Pakistani security personnel and civilians were killed in TTP attacks between 2021 and the end of 2025, and independent monitors recorded over a thousand violent incidents involving the group in 2025 alone, one of the worst years in more than a decade.

Q: What is the Haqqani network’s relationship to anti-India terrorism?

Among the groups on the Afghan frontier, the Haqqani network should most concern Indian threat assessment, because it has the clearest documented record of killing Indians. Founded by Jalaluddin Haqqani during the anti-Soviet jihad and later led by his son Sirajuddin Haqqani, the network operated for two decades as the most professionalized component of the Afghan insurgency, specializing in complex urban attacks and suicide bombings. It has been credibly linked to the suicide bombing of the Indian embassy in Kabul in 2008, an attack that killed dozens including senior Indian personnel, and investigators tied that operation to facilitation by Pakistan’s intelligence service. The network was also implicated in the 2009 embassy attack and the 2014 assault on the Indian consulate in Herat. With the Taliban’s return, Sirajuddin Haqqani became Afghanistan’s acting interior minister, placing the network’s leadership inside the Afghan state. The relationship to anti-India terrorism is therefore historical and structural rather than current and operational. The Haqqanis have killed Indians, and they maintain ties to the intelligence apparatus that built Lashkar-e-Taiba and Jaish-e-Mohammed. What they have not done since 2021 is direct fresh operations against India, because the network’s leadership is now absorbed in governing Afghanistan and managing the wars against the Islamic State and Pakistan. The network represents a latent capability and a worrying precedent rather than an active campaign.

Q: Has any India-focused terrorist attack been planned from Afghan soil?

No major India-focused terrorist attack in recent years has been credibly traced to planning conducted on Afghan soil, and this absence is one of the strongest pieces of evidence for the indirect-threat interpretation. The significant attacks on India and Indian interests over the past decade trace back to Pakistani territory, where the headquarters, the training infrastructure, and the leadership of Lashkar-e-Taiba and Jaish-e-Mohammed are located. The one genuine attempt to weaponize Afghan ground against India came not from the Taliban or the Haqqani network but from the Islamic State’s Khorasan branch, which tried to recruit Kashmiri youth and build a Kashmir franchise. That effort, in which the Kashmiri operative Aijaz Ahmad Ahangar was a central figure, comprehensively failed. The Islamic State never established a meaningful operational network in Kashmir, and the propaganda push did not translate into attacks. The honest conclusion is that Afghan soil has not functioned as a launchpad for terrorism directed at India, even though it has functioned for decades as a sanctuary for terrorism directed at Pakistan and at the West. This asymmetry is the empirical heart of the article’s argument: the spillover that reaches India is the indirect product of an ecosystem, not the direct output of an Afghan-based India operation.

Q: Who was Aijaz Ahmad Ahangar and why does his case matter?

Aijaz Ahmad Ahangar was a Kashmiri, born in Srinagar, who left Indian-administered Kashmir, spent years embedded in the militant networks of the Afghanistan-Pakistan frontier, and ultimately rose to a senior position in the Islamic State’s Khorasan operation. By Indian intelligence assessments he became one of the most prominent South Asians in that structure and worked as a recruiter attempting to draw Kashmiri youth toward the Islamic State. In February 2023 he was found dead in Kunar Province in eastern Afghanistan, in circumstances that were never clarified. His case matters for two reasons. First, he is the clearest available test of whether Afghan territory serves as a launchpad against India, and the verdict is largely negative, because his recruitment effort failed and the Islamic State never built a Kashmir network. Second, his death is the single contested instance of a relevant figure being killed on Afghan soil, and it is genuinely ambiguous. One reading attributes it to the India-linked targeted-killing campaign, which would make it the deepest geographic extension of that effort. Another reading attributes it to the Afghan Taliban’s own suppression of the Islamic State in Kunar and Nangarhar, a campaign that has killed many accused operatives. The evidence does not decisively settle the question, and the dedicated profile of the Kashmiri ISIS recruit treats this as an honest test of the limits of attribution.

Q: Did the shadow war’s targeted killings reach into Afghanistan?

No sustained or confirmed campaign of targeted killings reached into Afghanistan, and treating the frontier as a theater of the shadow war would misrepresent the record. The eliminations that define India’s covert campaign occurred in Pakistani cities, in Karachi apartments, Lahore mosques, Rawalakot prayer halls, Sialkot streets, and one case in North Waziristan. The only possible Afghan instance is the death of Aijaz Ahmad Ahangar in Kunar in 2023, and that case is contested, with the Taliban’s own suppression of the Islamic State at least as plausible an explanation as the campaign. The reason the campaign has not extended into Afghanistan is operational. The shadow war’s signature method is the close-range shooting, typically by men on motorcycles, which requires human assets physically present at the target and a permissive enough environment to approach and escape. Taliban-controlled Afghanistan, where outsiders are immediately conspicuous and the governing authority is hunting the same categories of target, is not such an environment. The one confirmed targeted killing on Afghan soil in recent years, the 2022 American drone strike that killed Ayman al-Zawahiri in Kabul, succeeded only because it was delivered from the air with the standoff capability of a superpower. The India-linked campaign has never demonstrated that capability, which is why the frontier’s relevance to the shadow war is structural rather than operational.

Q: How do weapons flow from Afghanistan into the wider militant ecosystem?

The weapons flow from Afghanistan is the most concrete and the most alarming of the cross-border dynamics. When the United States and its NATO partners withdrew in 2021, they left behind an enormous quantity of modern military equipment that had been supplied to the collapsed Afghan republic’s army, including assault rifles, machine guns, night-vision devices, optics, and communications gear. A substantial portion of that arsenal passed to the Taliban and from there leaked into the regional militant marketplace, a frontier economy that was already one of the world’s densest informal arms markets. Pakistani security officials have directly attributed the increased lethality of TTP attacks to the militants’ acquisition of this advanced American matériel. The danger for the broader region, and indirectly for India, is that weapons do not respect the distinction between anti-Pakistan and anti-India militancy. A night-vision device that enters circulation through the abandoned Afghan stockpile can end up in the hands of any group operating in the ecosystem. The flow runs along the same smuggling routes and high passes that defeat every attempt to seal the frontier, and it cannot be reversed, because equipment already in circulation cannot be recalled. This is the clearest single example of Afghan instability permanently upgrading the capability of the entire jihadist environment, and it is a worsening of the threat picture that no fence and no diplomatic engagement can undo.

Q: Is the Islamic State’s Khorasan branch a threat to India?

Khorasan Province, the Islamic State’s regional branch usually abbreviated ISKP or ISIS-K, represents a low-probability but high-consequence threat to India, and its actual record against Indian interests is thin. Formed in 2015 from defectors who found even the Taliban insufficiently extreme, the group is anti-Taliban, virulently anti-Shia, and hostile to Pakistan and India alike. It has carried out catastrophic mass-casualty attacks, including the bombing at Kabul airport during the 2021 evacuation and repeated strikes on Afghan Shia mosques and on the Russian embassy in Kabul. Its relevance to India lies in its attempt, largely through the recruiter Aijaz Ahmad Ahangar, to draw Kashmiri youth toward its banner and build a Kashmir franchise. That attempt failed almost completely. The Islamic State never established a meaningful operational network in Kashmir, and the young men exposed to its propaganda did not coalesce into a functioning cell. ISKP also matters in a counterintuitive way to the frontier’s overall stability: analysts note that the Afghan Taliban is reluctant to crack down too hard on the TTP partly because TTP fighters denied a home with the Taliban might defect to ISKP, their main rival. For Indian security, the group is a contingency to monitor rather than an active campaign, but its demonstrated capacity for spectacular violence means it cannot be dismissed.

Q: Does Afghanistan host the headquarters of Lashkar-e-Taiba or Jaish-e-Mohammed?

Afghanistan does not host the headquarters of Lashkar-e-Taiba or Jaish-e-Mohammed, and this fact is fundamental to understanding the frontier’s actual relationship to anti-India terrorism. Both organizations are Pakistan-based, Pakistan-headquartered, and Pakistan-protected. Lashkar-e-Taiba’s command center and its sprawling Markaz-e-Taiba complex sit at Muridke in Pakistani Punjab. Jaish-e-Mohammed’s center of gravity is at Bahawalpur, also in Punjab. The leadership of these groups, including Hafiz Saeed and Masood Azhar, has consistently been assessed as residing in Pakistan, not Afghanistan. The India operations of these outfits are run from Pakistani territory, not from Kandahar or Khost. The Afghan connection for Lashkar-e-Taiba and Jaish-e-Mohammed is therefore not a matter of current basing but of origin, ecosystem, and intermittent use. Their founding generations fought the Afghan jihad of the 1980s, their ideological vocabulary and training doctrines were forged there, and their fighters have at times used Afghan ground for training or transit when Pakistani scrutiny intensified. The broader instability the Afghan frontier radiates gives these groups cover, weapons, and recruits. But anyone searching for a Jaish-e-Mohammed headquarters on Afghan soil is looking in the wrong country, and the definitive guide to Jaish-e-Mohammed places the organization firmly within Pakistan.

Q: Why did India reopen its embassy in Kabul under Taliban rule?

India reopened its embassy in Kabul for reasons that are explicitly strategic rather than ideological or sentimental. For two decades India was a committed partner of the anti-Taliban order, backing the Northern Alliance in the 1990s and then becoming one of the largest development donors to the Western-backed republic after 2001. When the republic collapsed in August 2021, India closed its embassy and withdrew. The reversal began cautiously, with a small technical mission reopened in 2022 to manage humanitarian aid, and accelerated sharply in October 2025 when the Afghan acting foreign minister Amir Khan Muttaqi traveled to New Delhi, the most senior Taliban official to visit India since the movement’s return. During that visit India announced it would upgrade the technical mission to a full embassy, a step completed on the twenty-first of October, and by January 2026 a Taliban-appointed charge d’affaires was installed in New Delhi. India’s calculation rests on several pillars. A diplomatic foothold in Kabul provides a listening post for monitoring threats. Engagement lets New Delhi counterbalance the inroads that China has been making in Afghanistan. And the timing exploits the collapse of the Pakistan-Taliban relationship, giving India a stake in a rift that weakens its primary regional adversary. India has been careful not to extend formal recognition, and its engagement rests on calculation rather than trust, but the logic is clear: a foothold inside Afghanistan is safer for Indian interests than operating from the sidelines.

Q: How did the 2026 Afghanistan-Pakistan war change the frontier?

The cross-border war that erupted into full intensity in early 2026 marked the most dangerous deterioration in Afghanistan-Pakistan relations since the Taliban returned to power, and it reshaped the frontier in ways that bear directly on the regional terror picture. The conflict followed a sequence of escalations: deadly border clashes in October 2025, a fragile Qatar-mediated ceasefire that collapsed within weeks, a series of major attacks inside Pakistan, and then Pakistani airstrikes on militant camps in Afghan provinces in February 2026, which Afghan forces answered with attacks along the Durand Line. A Pakistani defense minister publicly described the two countries as being in a state of open war, and Pakistan launched a large-scale campaign of air and ground strikes. The consequences for the frontier were severe. Key crossings at Torkham and Chaman were closed, bilateral trade fell sharply, and large numbers of civilians were displaced and killed on the Afghan side. For the terror landscape, the war confirmed several of this article’s central points. It demonstrated that even a nuclear-armed state cannot wall off a hostile ecosystem next door. It tied down the Pakistani security establishment on its western flank, reducing the attention available to constrain anti-India outfits in Punjab. And it accelerated the India-Taliban rapprochement, because a Kabul at war with Islamabad has every incentive to cultivate Islamabad’s rival.

Q: Why does Pakistan accuse India of colluding with the Taliban?

As the Pakistan-Taliban relationship collapsed, Islamabad began to allege that the Afghan Taliban and India were colluding to support the TTP and Baloch separatist groups against Pakistan, framing the militancy on its western frontier as an Indian-sponsored proxy war. Pakistani military and civilian officials advanced this claim repeatedly through 2025. India has denied the allegation, and no credible public evidence has substantiated it. The claim is best understood as a strategic narrative rather than an established fact. It serves a clear purpose for Islamabad: it externalizes responsibility for a security crisis that is overwhelmingly the product of Pakistan’s own decades-long investment in jihadist proxies, an investment captured by the strategic-depth doctrine that has now produced a strategic catastrophe. The pattern is familiar from the shadow war itself, where Pakistan dismissed, minimized, and then reattributed the targeted killings on its own soil rather than confront what they revealed about the safe haven. The India-collusion charge on the Afghan frontier follows the same logic. When an uncomfortable security failure becomes undeniable, attribute it to the external enemy. The analytically serious assessment is that the TTP’s resurgence flows from the Afghan Taliban’s victory and from Pakistan’s own past choices, and that blaming New Delhi is a narrative convenience rather than a substantiated finding.

Q: How does the Afghan frontier connect to the rest of the shadow war?

The Afghan frontier is the western wall of the structure this series has mapped city by city, and its connection to the rest of the shadow war is best understood as a relationship between an ecosystem and the targets it produces. The eliminations that define India’s covert campaign happened in Pakistani cities, and the safe haven has been documented from Karachi’s anonymity to Rawalpindi’s garrison cover to the tribal zones of Waziristan. The Afghan frontier is where that Pakistani structure connects to a regional one. The men eventually shot in Pakistani cities were, in many cases, products of this belt: they trained in camps the Afghan jihad first established, they absorbed an ideology that crossed and recrossed the mountains for four decades, and they belonged to organizations whose survival depends on the strategic depth Afghanistan provides. The frontier also marks the point where the shadow war meets a parallel and far bloodier conflict, namely Pakistan’s overt war against the anti-Pakistan terrorists its own ecosystem produced. The two campaigns are distinct, but they share a root in the regional jihadist infrastructure. To map the safe haven and ignore the country next door would be to study a body without acknowledging its bloodstream, which is why a series about India’s covert campaign must account for the Afghan frontier even though that frontier contributes almost nothing to the campaign’s body count.

Q: What role do the frontier’s religious seminaries play in sustaining militancy?

A dense network of religious schools has lined the border districts of Khyber Pakhtunkhwa and Balochistan for decades, extending into the provinces on the other side of the line, and a consequential minority of these institutions function as the human renewal mechanism of the entire frontier ecosystem. Most such schools are ordinary places of religious instruction with no link to violence. The minority that matter teach a hardline interpretation of the Deobandi tradition, take in boys from impoverished families, and provide the food, shelter, and basic education that the state failed to deliver, while exposing some of their students to a worldview in which armed jihad is framed as a religious duty. The Taliban movement itself emerged in the early 1990s substantially from this seminary network, and the word taliban means students. Over the years the same institutional ecosystem has fed recruits into the Tehreek-e-Taliban Pakistan, into the Kashmir-focused outfits, and into the broader jihadist movement. Because these schools sit outside or at the margins of state regulation, and because closing them would mean confronting powerful religious constituencies, successive Pakistani governments have left the network largely intact. The significance for the spillover is that weapons can in principle be interdicted and money can in principle be traced, but the steady production of indoctrinated young men continues year after year, and it is the hardest input of the whole system to switch off.

Q: Which outside powers are involved in the Afghanistan-Pakistan frontier?

Several major powers now hold stakes in the frontier, and that internationalization has turned a once-contained South Asian problem into a crowded strategic theater. China has become the most consequential external actor in Taliban-ruled Afghanistan, pursuing mineral wealth, seeking to extend its Belt and Road investments, and pressing the Kabul government for guarantees against Uighur militants. Beijing’s deepening involvement is one of the explicit reasons New Delhi concluded that staying diplomatically absent from Kabul had become a liability. Iran, which shares a long western border, focuses on the security of the Shia Hazara minority targeted by the Islamic State, on managing refugee flows, and on water disputes along shared rivers. Russia formally removed the Taliban from its list of banned organizations and moved toward recognition, viewing the Islamic State’s Khorasan branch as the chief regional danger, especially after that group’s reach extended to attacks on Russian soil. The Central Asian republics to the north watch the frontier warily, fearing that instability and militant ideology will spill across their own borders. For India, this crowded field cuts both ways. More watching capitals raise the diplomatic cost of any state sponsoring cross-border terrorism. At the same time, the competition of external priorities makes the frontier harder to stabilize, because no single power has either the leverage or the will to impose order on the whole region.

Q: What does the Afghan spillover mean for the future of India’s security?

The Afghan spillover means that India faces, from its northwest, not a gun pointed at it but a furnace that keeps the region’s jihadist metal hot, and the distinction defines the kind of security challenge New Delhi must prepare for. A direct threat can be deterred, sanctioned, and negotiated away, because it has a return address. The indirect threat from the Afghan ecosystem has no return address, because it is the cumulative output of flows that no single actor controls. The weapons that leaked from abandoned arsenals are in permanent circulation. The ideological charge of the Taliban’s 2021 victory cannot be revoked. The instability that absorbs Pakistan’s security bandwidth will persist as long as the Pakistan-Afghanistan conflict does. India’s response has been pragmatic and multi-layered: a cautious diplomatic engagement with the Taliban that provides a listening post in Kabul, a refusal to extend formal recognition, and a continued covert campaign against the anti-India operatives who shelter in Pakistan rather than Afghanistan. The realistic forecast is that the frontier will remain unstable, that the ecosystem will continue to regenerate, and that the threat to India will continue to arrive indirectly, refreshed by Afghan disorder but executed from Pakistani soil. The frontier did not become a theater of the shadow war, and it is unlikely to. It will instead remain the unstable western ground on which the entire structure of the safe haven trembles, and the trembling itself, rather than any single Afghan plot, is what Indian security planning must account for in the years ahead.
