The important part of the agreement included Pakistan`s recognition of Bangladesh. Other issues were discussed: the repatriation of refugees to India and the release of Bangladeshi and Pakistani nationals stranded in both countries. Pakistan has agreed to host an unspecified number of bihari Muslims from Bangladesh. Pakistan has also agreed to send back to Bangladesh nearly 150,000 to 200,000 Bengali citizens of the new nation-state of Bangladesh. Among his failures was the least discussed also his worst. Until all the official recordings of the simla agreement signed on 2 July 1972 are published, we will never know what prompted Indira Gandhi to make such a damaging peace with Pakistan after the 1971 war. The Simla agreement and the subsequent Delhi agreement gave Pakistan everything it wanted: the territory it had lost in India during the war and the safe return of all its soldiers, without one of them being held responsible for the incandescent campaign launched in present-day Bangladesh. According to the Indian Ministry of Foreign Affairs, the Simla agreement was therefore “much more than a peace treaty that wants to reverse the consequences of the 1971 war (i.e. cause the withdrawal of troops and the exchange of prisoners of war) “It was a complete blue impression for the good-neighbourly relations between India and Pakistan. As part of the Simla Agreement, the two countries pledged to end the conflicts and confrontations that have affected relations in the past and to work towards lasting peace, friendship and cooperation. While the two heads of state and government clarified the general agreement at the summit, lengthy negotiations took place over 19 meetings in nearly two months, before the details were whipped. It is said that Prime Minister Indira Gandhi intervened several times to keep the talks going, and the final draft was approved by his cabinet.
The Bangladeshi government also expressed full satisfaction with the agreement and endorsed it. This is how the aforementioned agreement of August 29, 1972 was born. Prime Minister Indira Gandhi held the Shimla Summit with Pakistani President Zulfikar Ali Bhutto on 2 July 1972. The procedure is recorded in history as the Shimla Agreement, which imposed the process for the return of all Pakistani prisoners of war under their custody by India and also returns to Pakistan, 13,000 km2 of territory conquered in the Western theater. The agreement emphasizes respect for the sovereignty, territorial integrity, political independence and unity of the other. It also mentions non-interference in the internal affairs of the other and hostile propaganda. There is an overwhelming perception that India, in approving the conditions set by Pakistan, missed a great opportunity for which the Indian army had sacrificed the blood of its brave soldiers.
