The Non-Proliferation (NPT) Treaty is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to foster the peaceful uses of nuclear energy and to further the goal of disarmament. But NPT allows only those five nations manufactured and exploded a nuclear weapon before January 1, 1967 to retain their weapons after signing the treaty. India opposes this discriminative disarmament policy and argues for the complete ban of nuclear weapons and hence, still not a signatory of the NPT.
