The Treaty on the Prohibition of Nuclear Weapons was adopted at the United Nations on July 7th, 2017.

It outlaws everything to do with nuclear weapons.

It places nuclear weapons in exactly the same category as chemical and biological weapons, which are also banned by international treaty.

It establishes an international norm that treats nuclear weapons as unacceptable to the civilized world.

It makes it illegal in the countries that join it to “assist, encourage or induce, in any way, anyone to engage in any activity” that is prohibited by this treaty.

The importance of this treaty cannot be overstated. It does not by itself eliminate these weapons, but it will undoubtedly lead to their elimination.

The US should sign this treaty along with the rest of the world. Click on the links below to learn more.
