Americans assume that only select nations can legally build and stockpile nuclear weapons. Corporate media and the US Government constantly warn of grave danger if nations like Iran illegally develop nuclear weapons. They cite the 1970 Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the NPT. This is an international treaty to prevent the spread of nuclear weapons, to promote cooperation in the peaceful uses of nuclear energy, and to achieve worldwide nuclear disarmament. This treaty means that Iran and the United States should not have nuclear weapons. Nearly every nation in the world signed the NPT because it promised to eliminate nuclear weapons worldwide. The core purpose of the NPT is to eliminate nuclear arms, not to perpetuate the nuclear monopoly of a few countries.
