On November 29, 2009, India become one of the recognised nuclear power after it joined the Non Proliferation treaty India‟s new stand to be a nuclear weapon state within the NPT has triggered a debate that centres on continuity verses change. Those who support the change argue that India‟s willingness to join the NPT contains the potential to strengthen the NPT and add that by excluding a nuclear-armed, but non-proliferating India when it is willing to join the NPT would not strengthen the cause of non proliferation. Those who harp on continuity say that at a time when there is international debate over the very rationale of the NPT, why India is showing interest in it? The NPT has failed in checking proliferation of nuclear weapons and technology. Even then why does India want to become a part of this failed treaty?
