The International Humanitarian Movement for Nuclear Disarmament
The tides are turning. On July 7, 2017, the U.N. adopted the first-ever treaty imposing a comprehensive prohibition against nuclear weapons; more than 120 nations were in support. Inspired by past efforts that led to bans on land mines and cluster bombs, the treaty—negotiated without the nine nuclear-armed countries—reframes nuclear disarmament as a global health imperative and provides a vision for a nuclear weapons-free world.
The International Campaign to Abolish Nuclear Weapons (ICAN) mobilized civil society across more than 100 countries to create the political momentum at the U.N. to achieve the treaty. ICAN won the 2017 Nobel Peace Prize for raising awareness on the humanitarian impact of nuclear weapons. PSR’s global affiliate, International Physicians for the Prevention of Nuclear War (IPPNW), founded ICAN in 2007. PSR is a proud U.S.-partner of ICAN.
About the Nuclear Weapons Ban Treaty
On July 7, 2017, the U.N. adopted the Treaty on the Prohibition of Nuclear Weapons (TPNW), which comprehensively prohibits nuclear weapons and related activities. The medical community’s advocacy and research helped civil society and the international community devise public health solutions to the threat of nuclear weapons.

On July 20, the Chicago City Council passed a Back from the Brink resolution, becoming the 58th municipality in the USA to do so.
This week, over 80 delegations attended the First Meeting of States Parties to the Treaty on the Prohibition of Nuclear Weapons (1MSP).
With each new TPNW ratification, it becomes more clear that nuclear weapons are headed for the dustbin of history.
