Celebrate the second anniversary of the TPNW

We must never grow weary of working to support the principal international legal instruments of nuclear disarmament and nonproliferation, including the Treaty on the Prohibition of Nuclear Weapons [TPNW].

Pope Francis, November 2019, Japan

January 22, 2023 is the second anniversary of the entry into force of the Treaty on the Prohibition of Nuclear Weapons (TPNW). “Entry into force” means that the treaty’s provisions are binding in the 68 nations that have ratified the treaty; 30 other countries are moving through their ratification processes. 

From the UN: “The Treaty on the Prohibition of Nuclear Weapons (TPNW) includes a
comprehensive set of prohibitions on participating in any nuclear weapon activities.
These include undertakings not to develop, test, produce, acquire, possess, stockpile,
use or threaten to use nuclear weapons. The Treaty also prohibits the deployment of
nuclear weapons on national territory and the provision of assistance to any State in the
conduct of prohibited activities.”
