The United States brought nuclear weapons into the world. It is the only country to have used them, and it did so on innocent civilians.
Nuclear weapons are now many times more powerful than the fission bombs that destroyed Hiroshima and Nagasaki. They make no nation safer but imperil all nations and the planet we all live on. Nuclear weapons are intrinsically immoral.
Fifty years ago, the United States signed the Treaty on Nonproliferation of Nuclear Weapons. We joined the four other nuclear countries in 1968 to promise to work “in good faith” toward “complete disarmament,” while other nations that signed the treaty agreed to never obtain them.
