JULY 1,1968

Sixty-one nations, including the United States, Britain and the Soviet Union, signed the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) which set up systems to monitor use of nuclear technology and prevent more nations from acquiring nuclear weapons. 190 countries are now signatories; Israel, India and Pakistan remain outside the Treaty. North Korea joined the NPT in 1985, but in January 2003 announced its intention to withdraw from the Treaty.
