Pakistan-Afghanistan Conflict and Durand Line Rupture

Recent military clashes between Pakistan and Afghanistan have escalated sharply in 2026. Pakistan launched air and missile strikes deep inside Afghanistan, including Kabul and Kandahar. The Taliban retaliated by attacking multiple Pakistani military posts along the Durand Line. These conflicts followed a ceasefire mediated by Turkiye and Qatar after clashes in late 2025. Pakistan’s Defence Minister declared an open war on Afghanistan, signalling a serious breakdown in relations.

Political and Military Rupture

The conflict marks a threefold rupture. Politically, Islamabad and Kabul’s relationship has worsened despite the Taliban takeover in 2021. The Taliban failed to control the Tehrik-e-Taliban Pakistan (TTP), increasing militant attacks in Pakistan’s tribal areas. Militarily, Pakistan’s Deep State, which once supported the Taliban, now opposes it under new leadership. The open war declaration reflects Rawalpindi’s approval. Societally, tensions have risen over Afghan refugees in Pakistan, with government efforts to deport them facing Afghan resistance. This societal divide threatens long-standing ties.

Origins of the Divide

Pakistan helped create and nurture the Taliban in the 1990s. After the US withdrawal in 2021, Pakistan expected the Taliban to rein in the TTP. Instead, militancy surged. The Taliban’s refusal to act against TTP stems from historical refuge ties and tribal loyalties. The Islamic State Khorasan (IS-K) presence complicates matters, as the Taliban sees IS-K as a greater threat and tolerates TTP. Accusations fly both ways – Kabul blames Pakistan for exporting militancy, while Pakistan blames Afghanistan and India for internal problems.

Asymmetry and Strategic Implications

Pakistan holds military, economic, and political advantages over Afghanistan. Its air force and missile capabilities allow strikes deep inside Afghan territory. Afghanistan lacks an air force and navy and depends heavily on Pakistan for trade access through Karachi port. Pakistan can restrict Afghan trade by closing border passes. Pakistan’s regional influence, including ties with the US, is stronger. The Taliban’s limited military capacity restricts its response to Pakistan’s aggression. The conflict threatens long-term regional stability.

Future Prospects and Regional Impact

The Af-Pak relationship is now conflict-prone and fragile. Pakistan views Afghanistan as a strategic trap to avoid. The Taliban’s limited military power and economic dependence on Pakistan limit its options. The societal divide over refugees may fuel future tensions. Regional players like Turkiye and Qatar have tried mediating but peace remains elusive. The conflict’s impact extends beyond the two countries, affecting South and Central Asian security dynamics.
