For decades, Pakistan’s Afghan policy rested on a patron–proxy model that used Islamist militants to shape Kabul’s political order. Islamabad trained and armed jihadist groups, assuming the Taliban would remain dependent, but the Taliban’s return to power in 2021 shattered its willingness to subordinate itself to Pakistan’s notion that it stood superior. The Taliban now governs Afghanistan, and recent clashes show Islamabad and Kabul competing over Islamic governance along the Durand Line. Pakistan now faces a legitimacy crisis in which Islamist authority flows from territorial control rather than state sponsorship of militancy. Pakistan is not confronting insurgency spillover; it is confronting the unintended consequences of its own strategic success.
Pakistan is not confronting insurgency spillover; it is confronting the unintended consequences of its own strategic success.
In early 2026, Pakistan launched airstrikes on Kabul, Kandahar, and Afghan military positions, claiming self-defense against militant sanctuaries. Taliban forces retaliated with cross-border attacks and strikes on Pakistani security installations. These clashes turned counterinsurgency operations into direct confrontation, confirming that Pakistan now faces an Islamist rival rather than a proxy. The confrontation suggests that Pakistan’s long reliance on militant proxies can no longer deliver political control. Pakistani strategy assumed ideological affinity would translate into political compliance, but Taliban sovereignty eliminated the dependency on which that assumption rested.
Fighters from Tehrik-e-Taliban Pakistan triggered escalation in October 2025 by killing eleven Pakistani soldiers in Kurram district. Pakistan retaliated with strikes inside Afghanistan, prompting Taliban attacks on Pakistani border posts and establishing reciprocal retaliation.
Pakistan’s strategic-depth doctrine assumed Taliban compliance, yet Taliban authorities resisted Pakistani pressure, refused to recognize the Durand Line, and protected militants wanted by Islamabad.
Control over territory allowed the Taliban to negotiate rather than obey. Once insurgent movements govern, ideological alignment rarely ensures compliance. Since 2021, Taliban authorities have refused Pakistani requests to dismantle Tehrik-e-Taliban Pakistan sanctuaries in Afghanistan and instead encouraged negotiations between Islamabad and militant commanders. Taliban forces dismantled Pakistani border fencing and rejected the Durand Line as an international boundary. These actions demonstrate political autonomy. Ideological and ethnic ties limit Taliban willingness to act against these groups, leaving Pakistan confronted by militant networks beyond its control.
Taliban sovereignty reversed the patron–proxy hierarchy. After the Iranian Revolution of 1979, Tehran transformed from a client within regional power structures into an exporter of ideological authority that reshaped allied terrorist movements. Taliban rule now pulls militants toward Kabul’s control rather than Islamabad’s.
Neither side seeks sustained war, yet political and religious pressures catalyze escalation.
Competing Islamic narratives drive the confrontation. Pakistan frames military action as counterterrorism, while the Taliban portray Pakistani strikes as violations of sovereignty. Pakistani leaders face a dilemma attacking an Islamist government and risk weakening Pakistan’s religious credibility. Pakistan faces a paradox: The more forcefully it attempts to discipline the Taliban, the more it validates Taliban claims to Islamic legitimacy. Pakistan’s military superiority offers punishment, not control. A ground intervention could spark insurgency, while restraint enables militants to operate with confidence. Islamabad can punish Kabul but not force its compliance.
Neither side seeks sustained war, yet political and religious pressures catalyze escalation. Pakistan’s military superiority cannot impose compliance without strengthening Taliban narratives of resistance, while Taliban defiance enhances domestic legitimacy despite military weakness. If this trajectory continues, Taliban survival may show other militant movements that territorial control offers greater legitimacy than foreign sponsorship. The confrontation suggests that terrorist groups across the region may now seek state power instead of patronage.
Pakistan’s Afghanistan policy succeeded beyond what its architects expected. By helping the Taliban return to power, Islamabad enabled the rise of an Islamist government unwilling to remain subordinate to Pakistani strategy. The Durand Line now separates former partners competing for influence over the same political space. Pakistan no longer manages a proxy across the border; it confronts a rival shaped partly by its own past policies.
