Discuss how Pakistan's evolving strategic engagement with Afghanistan and the Gulf states affects India's security calculus in South and West Asia.

Pakistan's western policy is being recast on two fronts at once: a hardening line towards Taliban-ruled Afghanistan, and a formal defence alignment with the Gulf through the Strategic Mutual Defence Agreement (SMDA) signed with Saudi Arabia on 17 September 2025 [1]. Together these widen India's threat canvas from South Asia into West Asia.

Afghanistan: the collapse of "strategic depth"

• The decades-old doctrine of using Afghanistan as an anti-India rear buffer has unravelled; Kabul's Taliban rulers shelter the Tehrik-i-Taliban Pakistan (TTP), whose fighters move freely across the border [2].
• Rawalpindi has abandoned the "good Taliban/bad Taliban" distinction, but cross-border strikes have pushed Pakistan-Afghanistan ties towards open hostility [2].
• For India: a militarised, porous Durand Line raises risks of weapons proliferation — including US/NATO equipment left behind in 2021 — and of battle-hardened cadres being redirected eastward [2].

Gulf: alliance-building as compensation

• The SMDA treats aggression against one as aggression against both, giving Pakistan financial and energy cushioning while offering Riyadh a security guarantor [1][3].
• It risks extending Pakistan's nuclear-backed deterrence into Gulf rivalries, complicating India's ties with both Saudi Arabia and Iran [3].

India's recalibrated calculus

• India's six-million-strong diaspora, energy imports and the India-Middle East-Europe Corridor make Gulf stability a core national interest [3].
• The Ministry of External Affairs responded in measured terms, stating it would study the pact's implications and expecting mutual interests and sensitivities to be respected [1].
• Continued reliance on army-led foreign policy under Field Marshal Asim Munir keeps escalation risks high on India's western border [2].

Pakistan's westward turn reflects compensation for strategic failure rather than strength, since neither Kabul nor Riyadh resolves its structural fragility. India's optimal response is patient hedging: deepening defence, energy and labour-mobility ties with Gulf capitals so that no partner's Pakistan engagement comes at India's cost, while strengthening border surveillance and counter-terror diplomacy — an extension of its neighbourhood-first and Link West policies.
