The Cold War was never confined to Berlin, Cuba, or Washington and Moscow alone. The rivalry between the United States and the Soviet Union spilled into nearly every region of the world, and South Asia became one of its most consequential theatres. The subcontinent’s location, large population, and unresolved regional conflicts made it a prize that both superpowers wanted to influence. Over four decades, the choices made by India, Pakistan, and their neighbours during this period created alignments and rivalries whose effects are still visible in the region’s politics today.

Why South Asia mattered to the superpowers
South Asia sits at a strategic crossroads. It borders the Middle East, lies close to the Soviet Union’s southern frontier, and shares boundaries with China. For Cold War planners in both camps, gaining a foothold here meant the ability to monitor a rival, project power, and contain an opposing ideology. As one analysis of the era notes, the subcontinent had long been a central area of great power struggle for influence because of its geography and size.
What made the region especially attractive to manipulation was its internal divisions. The 1947 Partition left India and Pakistan locked in hostility, with wars over Kashmir already fought by the mid-1960s. Both newly independent states sought security and resources, and the superpower rivalry offered them a way to bargain for arms, aid, and diplomatic backing. In effect, the global contest gave regional actors leverage, and the regional rivalry gave the superpowers an entry point.
India and the politics of non-alignment
India’s first Prime Minister, Jawaharlal Nehru, chose a path that defined the country’s foreign policy for decades. Rather than join either bloc, India became a leading voice of the Non-Aligned Movement, which sought to let newly decolonised nations pursue independent policies without being dragged into the ideological war between capitalism and communism. Nehru believed India should avoid aligning with either superpower and instead maintain workable relations with both sides.
This stance was rooted in more than strategy. The anti-colonial worldview shared by much of the Indian political elite carried a deep scepticism of the capitalist West, which many associated with the imperial powers India had just freed itself from. That outlook made the Soviet Union appear, to many Indians, as a counterweight to imperialism. Yet non-alignment was always more flexible than neutral. India accepted American food aid when needed and Soviet support when it served national interests.
The drift towards Moscow
Several events nudged India closer to the Soviet Union. The 1962 war with China was a shock, and the growing Sino-Pakistani relationship that followed gave India a strong reason to seek a reliable major-power partner. When the United States and China began moving towards rapprochement in the late 1960s, and Washington tilted towards Islamabad, New Delhi saw the outlines of a hostile axis forming against it.
This is the context for the most important diplomatic decision India made during the Cold War.
The 1971 Indo-Soviet Treaty
On 9 August 1971, the foreign ministers of India and the Soviet Union signed the Treaty of Peace, Friendship and Cooperation. The timing was deliberate. East Pakistan was in turmoil, millions of refugees were pouring into India, and a war seemed increasingly likely. India needed assurance that it would not face the combined pressure of the United States, China, and Pakistan alone.
The treaty was widely seen as a significant departure from India’s earlier insistence on strict non-alignment. It contained a clause for mutual consultation in the event of a threat, which functioned as a powerful deterrent. According to the Indian government’s own commemoration of the agreement, it was not a military alliance but rather strengthened India’s strategic autonomy and its capacity for independent action.
Its practical effect was demonstrated within months. During the December 1971 war that led to the creation of Bangladesh, the United States sent a naval task force into the Bay of Bengal. The Soviet Union responded by dispatching its own warships to shadow the American force. Analysts have described the treaty as one of the most consequential foreign policy arrangements India entered into in the twentieth century, one that reshaped both the politics and the map of the subcontinent.
Pakistan in the Western camp
Pakistan made the opposite choice early and decisively. Facing what it viewed as an existential threat from a much larger India, and lacking the resources to build up its military alone, Pakistan turned to the United States. In May 1954 the two countries signed a Mutual Defense Assistance Agreement, and Pakistan went on to join two American-sponsored alliances.
SEATO and CENTO
Pakistan became a founding member of the Southeast Asia Treaty Organization (SEATO), a regional defence pact created by the Manila treaty of September 1954 and brought into force in February 1955. The following year it joined the Baghdad Pact, later renamed the Central Treaty Organization (CENTO), alongside Iran, Iraq, Turkey, and the United Kingdom. Being a member of both blocs earned Pakistan the description of “America’s most allied ally in Asia,” as it was the only Asian state belonging to both organisations.
The American rationale was containment of communism. Pakistan’s motives, however, were largely regional. Scholarship on the period observes that the alliances offered no real guarantee against a non-communist attack, meaning that the pacts did little to address Pakistan’s central security concern, which was India rather than the Soviet Union. Islamabad accepted this mismatch because the partnership brought substantial military hardware, including tanks, aircraft, and radar systems, and significant economic aid.
The limits of the alliance
The relationship was never as solid as it appeared. The United States consistently prioritised its global Cold War strategy over Pakistan’s specific quarrel with India. During the 1965 and 1971 wars, American arms embargoes left Pakistan feeling abandoned by its protector. These episodes taught Pakistani policymakers a lasting lesson: great-power relationships were transactional and could shift when global circumstances changed. This realisation pushed Pakistan to diversify its partnerships, drawing closer to China, with whom it had maintained friendly relations since the early 1960s.
The Soviet invasion of Afghanistan
If the 1971 treaty marked one turning point, the Soviet invasion of Afghanistan in December 1979 marked another, and arguably a more violent one. Fearing the collapse of a friendly communist government in Kabul and the rise of hostile Islamic forces on its southern border, the Soviet Union deployed over 100,000 troops to prop up the regime. The intervention brought the superpower rivalry directly to South Asia’s doorstep.
The invasion transformed Pakistan’s strategic value overnight. From a somewhat sidelined ally, it became a frontline state in the new phase of the Cold War. The United States, unwilling to confront the Soviets openly, chose to fund and arm the Afghan resistance through Pakistan.
Operation Cyclone and the Mujahideen
The covert American effort to arm the Afghan fighters was code-named Operation Cyclone. It became one of the longest and most expensive covert operations the CIA ever ran. Funding began modestly in 1980 and rose to roughly $630 million per year by 1987. Notably, American support actually predated the full invasion, with a presidential authorisation for limited assistance signed in July 1979.
Pakistan’s Inter-Services Intelligence (ISI) acted as the main channel for distributing weapons, money, and training to the Afghan Mujahideen, who operated from camps along the Pakistan-Afghanistan border. As one account of the war explains, the CIA provided weapons and money to the resistance through Pakistani intelligence, with the programme favouring the militant Islamic groups preferred by the regime of General Zia-ul-Haq. The later introduction of American Stinger missiles in 1986 gave the Mujahideen a way to counter Soviet airpower and helped tip the conflict.
India, meanwhile, took the opposite position. Consistent with its partnership with Moscow, New Delhi supported the Soviet-backed government in Kabul and offered it economic and diplomatic backing. This created yet another fault line, placing India on one side of the Afghan conflict and Pakistan and the United States firmly on the other.
The lasting legacy
The Cold War left South Asia with consequences that outlasted the Soviet Union itself. The most obvious was a hardened set of alignments: India tied to Moscow, Pakistan tied to Washington and Beijing. These patterns did not vanish when the Cold War ended. India’s perceptions of Russia even today remain partly shaped by the worldview formed in the Nehru era, as noted in an assessment by the George C. Marshall European Center for Security Studies.
The superpower rivalry also fed the region’s nuclear trajectory. Both India and Pakistan eventually developed nuclear weapons, driven in part by the security dilemmas the Cold War created and by doubts about whether superpower guarantees could be trusted. The Afghan war’s legacy proved even more troubling. The networks of armed fighters, weapons, and militant ideology nurtured during the 1980s did not simply disappear after the Soviet withdrawal in 1989; they contributed to instability in Afghanistan and the wider region for decades afterward.
Perhaps the deepest legacy is the habit of looking outward. The India-Pakistan rivalry became entangled with global power competition during the Cold War, and that pattern continues. Today, observers describe the same dynamic playing out in the context of US-China competition and renewed great-power involvement in the region. The actors and ideologies have changed, but the underlying tendency for regional rivalries to draw in outside powers, and for outside powers to exploit regional rivalries, remains remarkably consistent.
What do you think? Did non-alignment genuinely give India more freedom of action than Pakistan’s formal alliances gave it, or were both states ultimately shaped by forces beyond their control? And looking at the region today, how much of its current strategic landscape can still be traced directly to the choices made during these Cold War decades?
