Russia’s decision to sign a landmark military cooperation agreement with the Taliban has triggered a profound shift in South Asia’s strategic landscape.

This pact, finalised during the International Security Forum in Moscow, is the first formal defence treaty the Taliban regime has entered into with any foreign nation.

It goes far beyond symbolism, laying out structural cooperation in arms exchanges, technology transfers, licensing agreements, and joint development projects. For Kabul, this provides legitimacy and access to advanced military hardware, while for Moscow, it secures influence in Afghanistan and strengthens its buffer against extremist spill over into Central Asia.

The irony of this alignment is striking when viewed against history. In 1979, the Soviet Union invaded Afghanistan, only to be bled dry by mujahideen fighters funded by the United States and funnelled through Pakistan.

Those guerrillas eventually forced the Red Army’s withdrawal in 1989, hastening the Soviet collapse. Out of the ensuing civil war, the Taliban emerged in the early 1990s, composed of religious students and former mujahideen. Today, the descendants of those fighters are entering into defence cooperation with the very state their predecessors once fought to expel.

For Pakistan, this development is a strategic nightmare. Its military establishment long viewed Afghanistan as a source of “strategic depth” in the event of war with India, investing heavily in supporting the Taliban insurgency against Western-backed governments.

Yet since the Taliban’s return to power in 2021, relations have soured dramatically. Kabul has refused to recognise the Durand Line as the official border and has tolerated the Tehreek-e-Taliban Pakistan (TTP), which continues to launch deadly attacks inside Pakistan.

This has led to escalating hostilities, including border skirmishes, cross-border shelling, and Pakistani airstrikes on Afghan territory. Instead of providing depth, Afghanistan has become a liability, forcing Pakistan to stretch its military resources across two volatile fronts.

India, by contrast, has pursued a pragmatic engagement strategy. While avoiding formal recognition of the Taliban government, New Delhi has reopened its embassy in Kabul with a technical team and focused on humanitarian assistance such as wheat supplies, vaccines, and winter relief.

This development-first diplomacy has earned goodwill among Afghans and Taliban leaders. India has also explored structured trade channels, revitalised air freight corridors, and considered infrastructure investments through Iran’s Chabahar Port. By steering clear of interference in Afghan politics, India has revived its soft power and built a functional relationship with Kabul, positioning itself as a stabilising partner.

The Russia-Taliban pact dovetails neatly with India’s interests. Moscow remains New Delhi’s closest strategic partner, and its role as Kabul’s primary defence ally reduces the Taliban’s dependence on Chinese financing or Pakistani military support.

This alignment prevents Islamabad from weaponizing Afghan soil against India and forces Pakistan to divert resources to its western frontier. For India, the outcome is a major strategic gain: Pakistan’s grip on Afghanistan has collapsed, while India has quietly secured influence in its neighbour’s backyard through diplomacy and economic engagement.

This historical U-turn underscores how geopolitical tectonic plates are shifting in South Asia. Old animosities have given way to unexpected alliances, leaving Pakistan isolated and strategically weakened.

India, meanwhile, finds itself in a stronger position, consolidating its footprint in Central Asia and watching its primary adversary lose leverage in a region once considered its sphere of influence.
