Inter-Services Intelligence (ISI) is the premier intelligence service of Pakistan that is responsible for providing, managing, and co-ordinating military intelligence for the Pakistan Armed Forces. After an eminent intelligence failure in the Indo-Pakistani War of 1947, the ISI was established by Army Major-General R. Cawthome and Navy Commander S.M. Ahsan, in a view to co-ordinate military intelligence from each major service branch and provide an inter-service intelligence estimate. While intelligence operatives are recruited from each service, including civilians, the ISI has become very powerful and influential. Due to its wide range of intelligence operations and influence, the ISI has been criticised both internally and externally. The Director General for Inter-Services Intelligence is the head of the ISI and also the principal adviser to the Prime Minister and President of Pakistan; the ISI reports directly to the prime minister.
