Afghanistan & Pakistan:
A Border Drawn in 1893
and a War That Began in 2026
The conflict between Afghanistan and Pakistan is not a recent invention. It is the consequence of a colonial boundary that neither side fully accepts, a century of proxy wars and shifting alliances, and a fundamental disagreement about who controls the lands where their populations meet. In 2026, that disagreement became open war.
On February 21, 2026, Pakistan launched airstrikes on targets in eastern Afghanistan, triggering a rapid escalation that both governments would publicly define in maximalist terms: Pakistan declared an "open war" under the operation name Ghazab lil-Haq; the Taliban government in Kabul described its response as Rad-ul-Zulm — the repelling of oppression. But the seeds of this conflict were not planted in February 2026. They were planted in 1893, when a British official drew a line through Pashtun tribal lands and called it a border.
To understand why Afghanistan and Pakistan are at war, you need to understand what has always been contested between them — and why each escalation since 1947 has made the next one more likely.
The Durand Line: The Border That One Side Has Never Accepted
In 1893, Sir Mortimer Durand — Foreign Secretary of British India — and Afghan Emir Abdur Rahman Khan agreed on a line demarcating their respective spheres of influence. The line stretched approximately 2,600 kilometres through some of the most rugged terrain in Central Asia and, in the process, divided the Pashtun tribal homeland into two. The communities on either side of this line shared language, kinship ties, and centuries of continuous habitation. The line acknowledged none of this.
When Pakistan was created in 1947, it inherited the Durand Line as its northwestern frontier. Afghanistan, however, did not inherit the acceptance of it. Kabul has never formally recognised the Durand Line as a legitimate international boundary, viewing it as a relic of British imperialism imposed on Afghan sovereignty without genuine consent. This is not a fringe position in Afghan politics — it has been the consistent position of virtually every Afghan government, across every ideological orientation, since independence.
A border that one party refuses to recognise is not a border — it is a permanent source of conflict waiting for the conditions that will allow it to ignite. The Durand Line has been waiting since 1893.
The concept of Pashtunistan — a proposed homeland uniting Pashtun populations on both sides of the Durand Line — has been invoked by various Afghan governments as a political and symbolic challenge to Pakistani territorial integrity. Pakistan has consistently treated any support for Pashtunistan as an existential threat. This mutual suspicion has shaped everything that followed.

From Independence to Open War: A Timeline of Escalation
The current conflict did not emerge from a vacuum. It is the latest expression of a relationship defined by proxy warfare, strategic miscalculation, and the persistent consequences of the Durand Line dispute.
Pakistan's independence and the first rupture
Afghanistan opposed Pakistan's admission to the United Nations — the only country to do so. Border incidents followed through the 1940s–60s. Afghanistan's Daoud Khan government actively supported Pashtun separatist groups inside Pakistan. Pakistan's response was to cultivate Islamist networks in Afghanistan as a counterweight.
Soviet invasion and the mujahideen pipeline
The Soviet invasion of Afghanistan transformed Pakistan into the primary conduit for U.S. and Saudi support to Afghan mujahideen fighters. Pakistan's ISI became deeply embedded in Afghan militant networks — relationships that would outlast the Soviet withdrawal and reshape regional security for decades.
Pakistan backs the Taliban — for strategic depth
Pakistan supported the Taliban's rise to power in Afghanistan, motivated by the desire for a friendly western neighbour to offset Indian pressure, and to secure trade routes into Central Asia. The concept of "strategic depth" — using Afghanistan as buffer and rearguard space — became central to Pakistani security doctrine.
U.S. invasion and the double game
After September 11, Pakistan formally allied with the U.S.-led intervention while elements of its security establishment maintained relationships with the Taliban, which found sanctuary in Pakistan's tribal areas. The Taliban's Pakistani equivalent — the TTP — emerged and began attacking the Pakistani state from Afghan soil.
Taliban return and the TTP crisis
The Taliban's return to power in August 2021 dramatically worsened Pakistan's TTP problem. TTP attacks on Pakistani territory surged, conducted from sanctuaries inside Afghanistan that the Taliban government in Kabul refused to dismantle. Pakistan's demands that Kabul crack down on TTP went unmet; Afghanistan accused Pakistan of continued interference and border violations.
First direct strikes on Afghan territory
Pakistan conducted airstrikes on TTP targets in Kabul and other Afghan locations. Afghanistan retaliated with ground operations. Qatar and Turkey brokered a temporary ceasefire. It collapsed.
Open war begins
Pakistani airstrikes on militant targets in eastern Afghanistan triggered the current phase. Pakistani strikes reached Kabul and Kandahar. Afghan ground offensives and attacks on Pakistani border posts followed. Both sides adopted maximalist public framing: Ghazab lil-Haq (Pakistan) versus Rad-ul-Zulm (Afghanistan). Hundreds of civilians killed; over 100,000 displaced in early phases.
Why This War: What Both Sides Say — and What Both Sides Want
Pakistan's Position
Compel the Taliban to act against TTP sanctuaries
TTP attacks on Pakistani territory have killed hundreds of Pakistani soldiers and civilians since 2021. Islamabad views the Afghan Taliban's refusal to crack down on TTP as deliberate tolerance of a group waging war on Pakistan. The strikes are framed as defensive operations against terrorist infrastructure, not as aggression against the Afghan state.
Afghanistan's Position
Pakistani strikes violate sovereignty and the Durand Line dispute
The Taliban government views Pakistani airstrikes on Afghan territory as illegal aggression — a violation of sovereignty linked to Pakistan's longstanding refusal to recognise Afghan interests on the Durand Line. Kabul denies providing operational sanctuaries to TTP and frames its military response as legitimate self-defence.
Beneath the immediate military logic on both sides lies a set of structural contradictions that airstrikes alone cannot resolve. Pakistan cannot achieve sustainable security against TTP through military pressure on a government it does not recognise and cannot meaningfully negotiate with. Afghanistan cannot secure its sovereignty against Pakistani strikes while remaining economically isolated and diplomatically unrecognised. Both governments are, in a sense, fighting the wrong war against the wrong adversary — when the deeper problem is a border neither can accept and a relationship neither has the capacity to reset.
Where the Conflict Stands Now
As of June 2026, the conflict continues without resolution. Pakistani operations have targeted alleged militant hideouts in Khost, Kunar, and Paktika provinces, with UN-verified incidents documenting civilian casualties including children. Cross-border artillery and drone exchanges continue. Temporary pauses — including one around Eid-ul-Fitr, mediated by Saudi Arabia, Qatar, and Turkey — have not held.
Humanitarian Impact
Hundreds of civilians killed on both sides since February 2026. Over 100,000 internally displaced in early conflict phases, with further displacement from ongoing operations. UN reports have verified strikes killing non-combatants, including children, in Pakistani airstrikes on Afghan territory. The Taliban government's existing economic isolation has worsened the capacity of Afghan communities to absorb conflict-related disruption.
The UN, China, and several regional powers have called for de-escalation. China's interest is specifically economic — its Belt and Road investments in Pakistan and its broader interest in Central Asian stability give it leverage and motivation to push for dialogue, but no binding authority. The fundamental mistrust between Islamabad and Kabul — built over decades of proxy warfare, border violations, and competing narratives — has not been addressed by any of the diplomatic interventions to date.
The TTP Problem That Started This — and Has Not Been Solved
The Tehrik-i-Taliban Pakistan remains the proximate cause of the current escalation. Pakistani strikes have degraded specific TTP capabilities in Afghan territory, but have not eliminated TTP as an operational threat and have demonstrably not compelled the Afghan Taliban government to take action against them. If anything, Pakistani strikes have given the Taliban government a nationalist framing — defending Afghan sovereignty — that strengthens its domestic position while reducing its incentive to compromise on TTP.
This is the core strategic paradox at the heart of Pakistan's approach: the military tools being used to address the TTP problem are simultaneously worsening the conditions for the political solution that would actually resolve it.
What This Conflict Means Beyond the Border
The Afghanistan-Pakistan war does not occur in isolation. It is embedded within a set of larger dynamics that give it consequences far beyond the two countries directly involved.
Pakistan's internal security crisis predates and shapes its Afghan policy. TTP attacks have imposed significant costs on Pakistani civilian and military populations, generating domestic political pressure for visible military action. The strikes on Afghanistan are partly a response to that pressure — a demonstration of resolve against a threat that Pakistani governments have been unable to eliminate through domestic security operations alone.
Afghanistan's economic isolation means that the Taliban government has almost no economic leverage and limited diplomatic standing to deploy in negotiations. It is, in a sense, negotiating from pure military and ideological position — which makes compromise harder to reach and sustain.
China is the most significant external actor with genuine interest in stabilisation. Chinese economic investment in Pakistan, and Chinese interest in extending Belt and Road connectivity through Afghanistan into Central Asia, gives Beijing both the motivation and limited leverage to push for dialogue. China has called for restraint but has not yet deployed that leverage decisively.
India observes the conflict with a strategic interest in Pakistani distraction and a concern about regional instability. Gulf states — Qatar, Saudi Arabia, Turkey — are active as mediators but lack the authority to impose conditions.
Outlook
What Would Resolution Actually Require?
Sustained resolution of the Afghanistan-Pakistan conflict would require addressing layers of grievance that have accumulated over 130 years. In the near term, that means a genuine ceasefire framework with monitoring mechanisms that both sides accept. In the medium term, it requires substantive dialogue on three interlocking issues: border recognition (or at minimum, a formal framework for managing the Durand Line dispute), TTP sanctuaries (with verified action rather than denial from Kabul), and trade access (which gives both sides economic incentive to maintain stability).
None of these are achievable without sustained external facilitation and a fundamental change in the trust deficit between the two governments. As of mid-2026, neither condition is present. The most realistic near-term scenario is continued low-level conflict, intermittent ceasefires, and the accumulation of humanitarian costs that neither government will be held accountable for by any international mechanism.
The Durand Line will not be resolved in this generation. But the question of whether the conflict it generates produces open war or managed tension is still — barely — an open one.
