H.R. 1888, the Nuclear Weapons Abolition and Conversion Act of 2025, directs the United States to sign and eventually ratify the international Treaty on the Prohibition of Nuclear Weapons, contingent on all nuclear-armed nations beginning verifiable elimination of their arsenals. Once the President certifies that all nuclear-armed countries have started this process, the bill would redirect federal funding previously allocated for nuclear weapons programs toward climate change initiatives, including renewable energy development, worker retraining for nuclear industry employees, and addressing infrastructure needs like healthcare and housing. The legislation also calls for the U.S. to coordinate with other nuclear-armed nations to ensure the complete elimination of nuclear weapons globally. The bill was introduced by a group of Democratic representatives in March 2025 and has been referred to the House Committees on Foreign Affairs and Armed Services. This proposal represents a significant shift in U.S. nuclear policy, moving from deterrence-based strategy toward complete disarmament and domestic economic conversion.
