Western and Soviet involvement

The Soviet Union sided with the Bangladeshis, and supported the Indian Army and Mukti Bahini during the war. The Soviets thought that the independence of Bangladesh would weaken the position of its rivals—the United States and China. The USSR gave assurances to India that if a confrontation with the United States or China developed, it would take counter-measures. This assurance was enshrined in the Indo-Soviet friendship treaty signed in August 1971.

The United States supported Pakistan politically and with supplies. President Richard Nixon and his Secretary of State Henry Kissinger feared Soviet expansion into South and Southeast Asia. Pakistan was a close ally of the People's Republic of China, with whom Nixon had been negotiating a rapprochement. Nixon was planning to visit China in February 1972. Nixon feared that an Indian invasion of West Pakistan would give the Soviets control over the region. It would seriously undermine the global position of the United States and the regional position of America's new tacit ally, China. In order to demonstrate to China the bona fides of the United States as an ally, Nixon sent military supplies to Pakistan, routing them through Jordan and Iran, while also encouraging China to increase its arms supplies to Pakistan. The Nixon administration also ignored reports it received of the "genocidal" activities of the Pakistani Army in East Pakistan, most notably the Blood telegram. This prompted widespread criticism and condemnation both by Congress and in the international press."The Nixon Administration's South Asia policy... is beyond redemption.", wrote former USAID director John Lewis.
The United States introduced a resolution in the UN Security Council calling for a cease-fire and the withdrawal of armed forces by India and Pakistan. It was vetoed by the Soviet Union. In the following days Nixon and Kissinger tried to get India to withdraw, but they did not succeed.1971 War: How the US tried to corner India. Rediff.com. Retrieved on 2011-04-14. 

President Nixon requested Iran and Jordan to send their F-86, F-104 and F-5 fighter jets in aid of Pakistan. 

When Pakistan's defeat in the eastern sector seemed certain, Nixon deployed a carrier battle group led by the aircraft carrier USS Enterprise into the Bay of Bengal. The Enterprise and its escort ships arrived on station on 11 December 1971. According to a Russian documentary, the United Kingdom deployed a carrier battle group led by the aircraft carrier HMS Eagle to the Bay.

On 6 December and 13 December, the Soviet Navy dispatched two groups of cruisers and destroyers and a submarine armed with nuclear missiles from Vladivostok; they trailed U.S. Task Force 74 into the Indian Ocean from 18 December 1971 until 7 January 1972. The Soviets also had a nuclear submarine to help ward off the threat posed by USS Enterprise task force in the Indian Ocean.Birth of a nation. Indianexpress.com (2009-12-11).
