Indian Prime Minister Indira Gandhi had concluded that instead of taking in millions of refugees, India would be economically better off going to war against Pakistan. As early as 28 April 1971, the Indian Cabinet had asked General Manekshaw (Chairman of the Chiefs of Staff Committee) to "Go into East Pakistan". Hostile relations in the past between India and Pakistan added to India's decision to intervene in Pakistan's civil war. As a result, the Indian government decided to support the creation of a separate state for ethnic Bengalis by supporting the Mukti Bahini. RAW helped to organise, train and arm these insurgents. Consequently, the Mukti Bahini succeeded in harassing Pakistani military in East Pakistan, thus creating conditions conducive for a full-scale Indian military intervention in early December.
