Nuclear Non- Proliferation Treaty

The Treaty on the Non-Proliferation of Nuclear Weapons, also Nuclear Non-Proliferation Treaty (NPT or NNPT) is a treaty to limit the spread (proliferation) of nuclear weapons. The treaty came into force on 5 march 1970, and currently there are 189 states party to the treaty, five of which are recognised as nuclear weapon states: the United States, Russia, the United Kingdom, France, and China (also the five permanent members of the United Nations Security Council). Four hon-parties to the treaty are known or believed to possess nuclear weapons: India, Pakistan and North Korea have openly tested and declared that they possess nuclear weapons, while Israel has had a policy or opacity regarding its own nuclear weapons programme. North Korea acceded to the treaty, violated it, and in 2003 withdrew from it.
