Pakistan’s Strategic Depth Policy in Afghanistan: Militancy, Strategic Interests, and the Crisis of State Legitimacy

Abstract

This paper critically examines the structural evolution, strategic viability, and internal contradictions of Pakistan’s “strategic depth” policy in Afghanistan. Grounded in a critical security studies framework, the study investigates how the Pakistani military establishment’s historical reliance on selective militant proxies as foreign policy instruments has institutionalized a self-perpetuating war economy and induced a systemic crisis of state legitimacy. Utilizing securitization theory and Max Weber’s typology of legitimate authority, the analysis demonstrates how the perpetual securitization of the Pakhtun borderlands traditionally masked by narratives surrounding the Durand Line and Pakhtunistan has systematically depoliticized the periphery, subverted democratic governance, and replaced human development with institutionalized militarism. Through a critical assessment of the post-9/11 landscape, the study evaluates the fragmentation of former proxy networks into hostile anti-state insurgents specifically the Tehrik-i-Taliban Pakistan (TTP) and analyzes the strategic failure of the policy following the August 2021 Taliban resurgence in Kabul. It shows how the Islamic Emirate’s subsequent refusal to disown the TTP, coupled with India’s soft-power regional posture, has effectively inverted Pakistan’s traditional buffer zones into strategic vulnerabilities. Furthermore, the paper interrogates the ongoing policy paralysis regarding state-TTP negotiations, demonstrating that both military counter-insurgency operations and transactional peace deals lack public legitimacy in the absence of institutional accountability. The study concludes that Pakistan’s traditional strategic depth framework has lost global and domestic viability; without a decisive transition from a state-centric military-militant nexus to a human-centered security paradigm, any renewed military campaign risks being perceived not as a legitimate counter-insurgency drive, but as an extractive, coercive imposition on marginalized peripheral populations.
