The Nuclear Nonproliferation Treaty (NPT)

The Treaty on the Non-Proliferation of Nuclear Weapons (its full name) has been signed by all the nations of the world but three. It has been effective in providing assurances against proliferation of nuclear weapons since it came into force in 1970.

A number of organizations maintain websites relating to the treaty. They provide interpretations and additional links.

Every five years, a review conference is convened of all signatories to the NPT. The next two links provide background and the resulting proposals from the 2005 review conference.

When the Soviet Union broke up, nuclear weapons were stationed in newly independent Belarus, Kazakhstan, and Ukraine. The Lisbon Protocol brought those three states into the NPT, and the nuclear weapons were consolidated in Russia, which inherited the Soviet Union's nuclear weapons state status under the NPT.
