In a rare moment of Cold War cooperation, sixty-two nations gathered in 1968 to sign a treaty designed to prevent nuclear proliferation and ensure the world never faced an atomic apocalypse.
The Treaty on the Non-Proliferation of Nuclear Weapons was signed on July 1, 1968, in a simultaneous ceremony across Washington, London, and Moscow. At the height of the Cold War, world leaders realized that the survival of humanity depended on limiting the spread of nuclear technology.
