Pakistan is confronting rising blowback from its long‑standing strategy toward Afghanistan as militant violence, diplomatic strain and security concerns escalate along the shared border, analysts say. What was once viewed in Islamabad as a way to secure influence over its western neighbour has increasingly become a source of internal instability, critics argue.
After the Taliban’s return to power in Kabul in 2021, Pakistan sought a strategic relationship with the new regime, expecting that ideological ties and historical cooperation would translate into shared action against cross‑border threats. However, that calculus has faltered, and Islamabad’s efforts to manage the region’s security landscape have increasingly met with challenges that analysts describe as policy blowback.
Security officials in Pakistan point to a steady rise in militant attacks along the Afghan border, with insurgent groups like the Tehreek‑e‑Taliban Pakistan (TTP) blamed for deadly violence in provinces such as Khyber Pakhtunkhwa and Balochistan. A recent ambush in Karak district in which suspected militants killed police officers highlighted the persistent threat and intensifying danger posed by such groups.
Despite Islamabad’s longstanding view of the Taliban as a strategic partner, militants linked to the TTP and other organisations continue to operate, sometimes staging attacks inside Pakistan after crossing from Afghan territory. Pakistani officials say this reflects a failure by Kabul’s authorities to curb groups that threaten Islamabad’s security — a central grievance in bilateral relations.
In 2025, high‑stakes peace talks between Pakistan and the Afghan Taliban regime repeatedly broke down, even after initial ceasefires had been negotiated. Pakistani authorities pressed the Afghan leadership to take concrete action against the TTP and other militants believed to use Afghan soil as a safe haven. However, Kabul refrained from committing to written guarantees, a sticking point that ultimately stalled negotiations.
Defence officials in Pakistan publicly warned that continued attacks originating from across the border could trigger stronger responses, underscoring Islamabad’s growing frustration with what it deems ineffective diplomatic engagement.
For decades, Pakistan’s policy toward Afghanistan was shaped by a “strategic depth” doctrine — the idea that friendly governance in Kabul would provide Islamabad with influence and leverage in regional geopolitics. But many analysts now describe this strategy as backfiring, with militant networks once tolerated or indirectly supported resurfacing as destabilising forces that undermine Pakistan’s own security.
This reversal has prompted criticism from political commentators in Pakistan, who argue that Islamabad misjudged the evolving priorities of the Afghan Taliban and overestimated its ability to control outcomes through ideological affinity. The Taliban leadership, experts note, has diversified its foreign relations and is increasingly resistant to external pressure, including from Pakistan.
The domestic response to these developments reflects deep concern across Pakistan. Some political figures have criticised the military leadership’s handling of foreign policy, pointing to inconsistencies and perceived double standards in how Islamabad addresses cross‑border militancy while decrying external threats from regional rivals.
Security analysts stress that the rebound of militant violence not only jeopardises border areas but also strains Pakistan’s broader diplomatic standing. Without effective cooperation from Kabul, Pakistan may be compelled to adopt a more hard‑nosed approach, including stricter border controls and intensified counterterrorism operations.
The ongoing tensions between Pakistan and Afghanistan — fuelled by mutual distrust and unresolved security grievances — have broader implications for South Asian stability. Militancy spillover, failed diplomatic efforts, and deteriorating bilateral ties risk undermining peace in a region already beset by geopolitical competition and internal conflicts.
Observers caution that unless both Islamabad and Kabul find a mutually acceptable framework to address cross‑border terrorism, the cycle of conflict and retaliation could intensify, with repercussions not just for the two neighbours but for wider regional security.
