Pakistan 's nuclear policy was significantly affected by the 1965 war with India . The 1971 war and India 's nuclear program played a role in Pakistan 's decision to go nuclear . India and Pakistan both decided not to participate in the NPT . Pakistan 's nuclear policy became fixated on India because India refused to join the NPT and remain opened to nuclear weapons . Impetus by Indian actions spurred Pakistan 's nuclear research . After nuclear weapons construction was started by Bhutto 's command , the chair of Pakistan Atomic Energy Commission Usmani quit in objection . The 1999 war between Pakistan and India occurred after both acquired nuclear weapons . It is believed by some that nuclear weapons are the reason a big war has not broken out in the subcontinent . India and Pakistan still have a risk of nuclear conflict on the issue of war over Kashmir . Nuclear capability deliverable by sea were claimed by Pakistan in 2012 . The aim was to achieve a " minimum credible deterrence " . Pakistan 's nuclear program culminated in the tests at Chagai . One of the aims of Pakistan 's programs is fending off potential annexation and maintaining independence
