How did Pakistan lose the Indo-Pakistani war of 1971 despite having complete support from NATO and technological superiority over Indians?

It is not just about how India won, but rather how Pakistan just misunderstood it.

India had nothing much, no support from Soviet. NATO and the United States had confirmed their support to Pakistan but they did not send any aids at all. Even so, UK and USA had planned to blockade India

Unfortunately, Pakistan only have themselves to blame.

The Indo-Pakistani conflict was sparked by the Bangladesh Liberation war, a conflict between the traditionally dominant West Pakistanis and the majority East Pakistanis. The Bangladesh Liberation war ignited after the 1970 Pakistani election, in which the East Pakistani Awami League won 167 of 169 seats from East Pakistan and thus secured an absolute majority in the 313-seat lower house of the Majlis-e-Shoora (Parliament of Pakistan). Awami League leader Sheikh Mujibur Rahman presented the Six Points to the President of Pakistan and claimed the right to form the government. After the leader of the Pakistan Peoples Party, Zulfikar Ali Bhutto, refused to yield the premiership of Pakistan to Mujibur, President Yahya Khan called the military, dominated by West Pakistanis, to suppress dissent in East Pakistan.

After the convening of the National Assembly was postponed by Yahya Khan on 1 March, the dissidents in East Pakistan began targeting the ethnic Bihari community which had supported West Pakistan. In early March 1971, 300 Biharis were slaughtered in rioting by Bengali mobs in Chittagong alone. The Government of Pakistan used the 'Bihari massacre' to justify its deployment of the military in East Pakistan on 25 March, when it initiated its Operation Searchlight.

Mass arrests of dissidents began, and attempts were made to disarm East Pakistani soldiers and police. After several days of strikes and non-co-operation movements, the Pakistani military cracked down on Dhaka on the night of 25 March 1971. The Awami League was banished, and many members fled into exile in India. Mujib was arrested on the night of 25–26 March 1971 at about 1:30 am (as per Radio Pakistan's news on 29 March 1971) and taken to West Pakistan. The next action carried out was Operation Searchlight, an attempt to kill the intellectual elite of the east.

On 26 March 1971, Ziaur Rahman, a major in the Pakistani army, declared the independence of Bangladesh on behalf of Sheikh Mujibur Rahman. In April, exiled Awami League leaders formed a government-in-exile in Baidyanathtala of Meherpur. The East Pakistan Rifles, a paramilitary force, defected to the rebellion. Bangladesh Force namely Mukti Bahini or Bangladesh Force consisting of Niyomito Bahini (Regular Force) and Gono Bahini (Guerilla Force) was formed under the Commander-in-Chief (C-in-C) General Mohammad Ataul Ghani Osmany.

Initially, Pakistan was the dominant before the war. However, Pakistanis in the East(Bengali's) hated the West (predominantly Punjabi's). They thought that Western Pakistanis were trying to dominate them in everything. India was not a fool at all and they knew it.

India then decided to allow troops to attack Pakistan in any fronts. Meanwhile, Nixon believed India would fail. But he was wrong, India was winning. So he requested China. But China didn't help Pakistan because China feared the Soviet attacks as well as India’s awareness over China’s actions

However, I have noted: Pakistanis should only blame themselves for the mess. It was them who granted victory for India by mass killing on each other in today-Bangladesh

About our US involvements, it was true that there were some ships deployed into the Indian Ocean (Bay of Bengal)

The United States supported Pakistan both politically and materially. President Richard Nixon and his Secretary of State Henry Kissinger refused to use rhetoric in a hopeless attempt to intervene in a large civil war. They needed Pakistan to help stop Soviet expansion into South Asia in informal alliance with India. Pakistan was a close formal ally of the United States and was also on good terms with the People's Republic of China, with whom Nixon had been negotiating a rapprochement and where he intended to visit in February 1972. Nixon feared that an Indian invasion of West Pakistan would mean total Soviet domination of the region, and that it would seriously undermine the global position of the United States and the regional position of America's new tacit ally, China. Nixon encouraged countries like Jordan and Iran to send military supplies to Pakistan 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 the United States Congress and in the international press.

Then-US ambassador to the United Nations George H.W. Bush—later 41st President of 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. The following days witnessed a great pressure on the Soviets from the Nixon-Kissinger duo to get India to withdraw, but to no avail.

It has been documented that 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 Task Force 74 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 her final deployment. Eagle was paid off by January 1972 at Portsmouth, and was stripped of reusable equipment (radars and missile systems primarily).

Because of the sudden rise of sympathies towards India, Nixon could not go further.

Personally I agree with Bangladeshis. Pakistan better start resolving their internal problems. They have caused too much harm on themselves and they better learn something before its too late.

4 failed wars had shown us that Pakistan is bull headed about India and they will put themselves in harms way even if they can inflict a little bit of damage to its sworn enemy, India. With a corrupt Government and a fundamentalist attitude on the rise, it has all the ingredients to become an international nightmare in the future.

Pakistan will continue to lose if they don't mend their ways.
