India's call for a ban on nuclear testing in 1954 led to the Partial Test Ban Treaty (PTBT). However, in the 1960s, with the security situation deteriorating in its neighborhood, many Indian politicians and bureaucrats felt the need to acquire nuclear weapons in order to deter external nuclear threats. When the NPT was opened for signature, India underlined the lack of a clear plan for nuclear disarmament as a reason to not sign the treaty. Although India remain firm determinant in No First Use policy. Similarly, Prime Minister Rajiv Gandhi pitched in for a 'Nuclear-Weapon Free and Non-violent World Order' at the third special session on Disarmament at the UN General Assembly in June 1988. Sametime, Pakistan had made significant progress in its own nuclear weapons program and unsuccessful attemps in the negotiations on Comprehensive Test Ban Treaty (CTBT) and indefinite extension of NPT in 1995, Indian tilts from its nuclear policy and tested its nuclear bomb in 1998.
