The UN Treaty on the Prohibition of Nuclear Weapons reached the required 50 states parties for its entry into force, and it  became law on January 22, 2021. This is having an impact even on nations not yet party to the treaty. The movement is growing. There are currently 93 signatories and 69 states parties, with activists the world over urging their countries to join.

The U.S. government keeping nuclear weapons in Germany, Belgium, Netherlands, Italy, Turkey, and the UK is not supported by the people of those nations, and is arguably already illegal under the Treaty on the Non-Proliferation of Nuclear Weapons.

As is stated very clearly in the U.S. Law of War Manual, U.S. military forces are bound (and the same is true for other countries) by international treaties even when the U.S. does not sign them, when such treaties represent “modern international public opinion” as to how military operations should be conducted. And already investors representing more than $4.6 trillion in global assets have divested from nuclear weapons companies because of the global norms that are shifting as a result of the TPNW.
