“The entry into force of the Treaty on the Prohibition of Nuclear Weapons in January 2021 was an extraordinary achievement and a step towards the eventual elimination of nuclear weapons.”

– António Guterres, UN secretary-general, 2021

As more and more nations join the TPNW over time, its norms will grow stronger, and the pressure on nuclear-armed nations to conform to them will intensify. To date, over half of the world’s nations have joined the treaty.

It offers a powerful alternative to a world in which threats to inflict mass destruction are allowed to prevail. It presents a pathway forward at a time of alarming crisis.
