The latest round of fighting between Afghanistan and Pakistan has once again exposed one of South Asia's most volatile and unresolved rivalries.

Pakistani airstrikes inside Afghan territory, justified by Islamabad as operations against militant sanctuaries, have resulted in civilian casualties according to Afghan authorities and international reporting, further inflaming public anger across Afghanistan.

Kabul has condemned the strikes as a violation of its sovereignty and warned that repeated military incursions risk turning a long-simmering dispute into a broader regional crisis. Although Pakistan argues that cross-border militant groups, particularly the Tehrik-i-Taliban Pakistan (TTP), operate from Afghan territory, Afghanistan maintains that Pakistan cannot use security concerns as a license to violate another country's borders. From the Afghan perspective, repeated airstrikes reinforce a pattern in which Islamabad seeks military solutions to political problems while disregarding Afghan lives and territorial integrity.

The roots of this confrontation stretch back well before the creation of modern Afghanistan and Pakistan as neighboring states. At the heart of the dispute lies the Durand Line, drawn by the British in 1893 to separate British India from Afghanistan. Successive Afghan governments have questioned the legitimacy of this colonial boundary, arguing that it divided Pashtun tribal communities without their consent. Pakistan, inheriting the frontier after independence in 1947, considers the Durand Line its internationally recognized border.

This disagreement has remained unresolved for decades and continues to shape security calculations on both sides. Afghanistan was also the only country to oppose Pakistan's admission to the United Nations in 1947, reflecting its refusal to accept the border settlement inherited from British rule. Since then, relations have oscillated between uneasy cooperation and outright hostility. Every major political transformation in Afghanistan—from the Soviet invasion to the civil war, the rise of the Taliban, the American intervention after 2001, and the Taliban's return to power in 2021—has influenced bilateral relations.

For many Afghans, Pakistan has long been viewed not merely as a neighbor but as a state deeply involved in Afghan domestic affairs. Afghan political leaders across ideological lines have frequently accused Islamabad of supporting armed groups to secure strategic influence in Afghanistan. During the anti-Soviet jihad, Pakistan became the principal staging ground for the Mujahideen.

Later, the Taliban movement emerged largely from religious seminaries in Pakistan and received varying degrees of support from Pakistani institutions during the Afghan civil war. These historical experiences have fostered deep mistrust among ordinary Afghans, many of whom believe Pakistan has consistently sought a weak and dependent Afghanistan rather than a stable and sovereign neighbor.

Pakistan rejects these accusations and argues that it has paid an enormous price for decades of instability spilling over from Afghanistan. Millions of Afghan refugees have lived in Pakistan since the Soviet invasion, while terrorist attacks inside Pakistan have claimed thousands of civilian and military lives. Islamabad insists that militant organizations exploiting Afghan territory present an existential threat to Pakistan's security and therefore require decisive action. This
