The Treaty on the Non-Proliferation of Nuclear Weapons, also Nuclear Non-Proliferation Treaty (NPT or NNPT) is a treaty to limit the spread of nuclear weapons, opened for signature on July 1, 1968. There are currently 189 countries party to the treaty, five of which have nuclear weapons: the United States, the United Kingdom, France, Russia, and the People's Republic of China (the permanent members of the UN Security Council) .
Only four recognized sovereign states are not parties to the treaty: India, Israel, Pakistan and North Korea. India and Pakistan both possess and have openly tested nuclear bombs. Israel has had a policy of opacity regarding its own nuclear weapons program. North Korea acceded to the treaty, violated it, and later withdrew.
Now US is saying without NPT we can go ahead with this so called deal but it will not work with permanant members of security council except US for its own interest, besides that India, Pakistan, and North Korea - have not signed the CTBT aswell How dangerous it could be to keep our weapons down before the enemy does? or is this america wants us to do... simple check and mate "chit bhi meri aur pat bhi" then, when everytime pakistan will threaten us Pizza man will run to US for help?
