Pakistan’s decision to bomb Kabul and Kandahar on February 27-28, 2026 — declaring an “open war” against the Taliban government — represents one of the most dramatic ruptures in South Asian geopolitics since the Taliban’s return to power in August 2021. Pakistan’s Defence Minister Khawaja Asif’s proclamation that the neighbours are now in “open war” marks the formal end of what was once one of the region’s most strategically consequential relationships: Islamabad’s decades-long cultivation of the Afghan Taliban as a force for strategic depth against India.
For India, this development presents both opportunities and risks that UPSC aspirants must analyse with rigour. India has been systematically deepening its engagement with the Taliban government over the past two years — hosting Taliban Foreign Minister Amir Khan Muttaqi, allowing the Taliban to operate a diplomatic mission in New Delhi, and expanding trade and connectivity relationships through Chabahar and other channels. Pakistan’s Defence Minister Asif has explicitly accused the Taliban of acting as a “proxy for India,” a charge that, while reflecting Islamabad’s strategic frustration, underscores the extent to which India’s Afghanistan policy has shifted the regional balance.

The humanitarian, counter-terrorism, and regional stability dimensions of this conflict are equally significant. Pakistan’s airstrikes on civilian-populated cities, the Taliban’s retaliatory cross-border attacks, and the cycle of violence threaten to destabilise an already fragile Afghan state, with inevitable spillovers for refugee flows, narcotics trafficking, and the operations of groups like the Tehreek-e-Taliban Pakistan (TTP).

Background and Context: The Architecture of a Fractured Alliance
The Pakistan-Taliban relationship spans more than three decades. During the Taliban’s first period in power (1996-2001), Pakistan was one of only three countries — alongside Saudi Arabia and the UAE — to formally recognise the Islamic Emirate. Pakistan provided the Taliban with sanctuary in Quetta during the post-2001 insurgency period, and the Quetta Shura, the Taliban’s senior leadership council, operated from Pakistani soil with the tacit acquiescence of the ISI. This relationship was premised on Pakistan’s theory of “strategic depth” — the notion that a friendly Afghanistan would prevent India from exercising influence on Pakistan’s western flank and provide strategic manoeuvre space in the event of a conventional conflict with India.
Five Important Key Points
- The immediate trigger for Pakistan’s February 2026 airstrikes was an Afghan Taliban cross-border attack on Pakistani border troops on February 27, which was itself retaliatory for earlier Pakistani strikes — a classic tit-for-tat escalation cycle that has been intensifying since deadly border clashes in October 2025 killed over 70 people on both sides.
- The Tehreek-e-Taliban Pakistan, a distinct but ideologically aligned organisation, has escalated attacks inside Pakistan dramatically since the Afghan Taliban returned to power in 2021, with the Pak Institute for Peace Studies reporting at least 400 fatalities, predominantly among security personnel, from TTP attacks in 2025 alone.
- The Durand Line — the 2,640-kilometre border established by the British in 1893 — remains unrecognised by successive Afghan governments, and the Taliban’s refusal to acknowledge it has transformed this historical dispute from an insurgency-era non-issue into a state-level sovereignty conflict.
- India hosted Taliban Foreign Minister Amir Khan Muttaqi in 2025 and has allowed a Taliban diplomatic mission to operate in New Delhi, representing the most significant India-Taliban engagement since India evacuated its diplomatic missions from Afghanistan in 2021.
- Iran offered to “facilitate dialogue” between Pakistan and Afghanistan on February 28, while Saudi Arabia, China, and Turkey have all been involved in mediation efforts, illustrating the broader regional dimension of this bilateral conflict.
The Strategic Depth Doctrine: A Concept That Has Backfired
Pakistan’s theory of strategic depth — articulated most explicitly by former Army Chief General Mirza Aslam Beg in the late 1980s and early 1990s — held that Pakistan needed a friendly Afghanistan to ensure it would not be “sandwiched” between hostile India and a pro-Indian Afghanistan in a military confrontation. The strategy required the cultivation of Pashtun tribal networks and the support of an Islamist Afghan movement that would be organically hostile to Indian influence.
The theory has comprehensively failed. The Afghan Taliban, once in power as a state, have behaved according to the logic of Afghan nationalism rather than Pakistani patronage. The Durand Line dispute, which was manageable when the Taliban were an insurgency dependent on Pakistani support, has become a central interstate conflict now that the Taliban are a government defending territorial sovereignty. The strategic depth doctrine assumed Pakistani leverage over the Taliban that simply does not exist in the current configuration.
The TTP Factor: Pakistan’s Most Immediate Security Crisis
The TTP’s intensification since 2021 represents Pakistan’s most acute security challenge and the proximate cause of the current conflict. The group seeks to replicate the Afghan Taliban’s model in Pakistan’s tribal belt, particularly in Khyber Pakhtunkhwa and the erstwhile FATA districts. Pakistan has repeatedly demanded that the Afghan Taliban suppress or hand over TTP leadership sheltering on Afghan soil, and the Taliban government’s consistent refusal — citing non-interference in the affairs of foreign groups — has been the primary source of bilateral friction.
The TTP’s escalation illustrates a broader pattern in which ungoverned or partially governed spaces — whether in Afghanistan’s border regions or in Pakistan’s tribal areas — become incubators for transnational militancy. For India, the TTP’s strengthening is not a purely Pakistan-Afghanistan bilateral concern: the group maintains ideological networks with Kashmir-oriented militant organisations and contributes to the general instability of the Pakistan security establishment that affects India’s security environment.
India’s Strategic Opportunity and the Limits of Engagement
India’s deepening engagement with the Taliban represents a pragmatic recalibration that acknowledges the reality of Afghan governance without formally endorsing Taliban policies on women’s rights, education, or minority treatment. India’s core interests in Afghanistan — connectivity through Chabahar and the International North-South Transport Corridor (INSTC), economic investment in Afghan minerals and infrastructure, and the prevention of Afghanistan’s re-emergence as a base for anti-India militancy — require some form of working relationship with whoever governs Kabul.
The Pakistan-Taliban conflict expands India’s strategic space in Afghanistan, but also creates risks. A severely weakened or destabilised Afghanistan — one that descends into prolonged civil conflict following sustained Pakistani airstrikes — would undermine India’s connectivity investments, generate refugee flows that could destabilise Central Asia, and potentially create new ungoverned spaces exploitable by groups hostile to India.
Regional and International Dimensions
China’s statement that it was “working with” both countries while calling for calm reflects Beijing’s interest in preventing a conflict that could destabilise the China-Pakistan Economic Corridor (CPEC), whose western route passes through Balochistan adjacent to the Afghanistan border. Saudi Arabia’s mediation role — which recently secured the release of three Pakistani soldiers captured by Afghanistan — reflects Riyadh’s traditional role as a backstop for Pakistan’s security relationships. Iran’s offer to facilitate dialogue reflects Tehran’s vulnerability to any spillover that affects its long eastern border with Afghanistan.
Way Forward
India should continue its calibrated engagement with the Taliban government, maintaining functional diplomatic and trade relations without formal recognition, and using its position to advocate for a negotiated settlement to the Pakistan-Taliban conflict through multilateral forums including the Shanghai Cooperation Organisation, of which India, Pakistan, and Iran are all members. India must also work to prevent the Pakistan-Taliban conflict from generating new spaces for anti-India militant activity, including through enhanced intelligence sharing with Central Asian partners and continued investment in the Chabahar-INSTC connectivity corridor as an alternative to Pakistan-controlled routes.
