Comprehensive Nuclear Test Ban Treaty

The Comprehensive Nuclear Test Ban Treaty (CTBT) is considered to be the "holy grail" of nuclear arms control. Ratifying the CTBT would institute a global ban on all nuclear weapons explosions on the earth’s surface, underwater and underground. Banning these test explosions drastically reduces any chances of developing new nuclear weapons technologies and programs.

The CTBT has now been signed by 183 nations and ratified by 158 including Russia and U.S. allies. However, the CTBT will not go into effect until it is ratified by eight specific countries including the United States, China, India and Iran. U.S. ratification would spur these key counties to ratify and would reinforce the global taboo against nuclear testing.
