Mission Statement

The Physicists Coalition for Nuclear Threat Reduction works to reduce the threats from nuclear weapons by mobilizing advocacy within the physical sciences communities in the United States and internationally. Given the civilization-ending potential of the use of nuclear weapons, we advocate for substantive changes in nuclear arsenals, force postures, and declaratory policies. We also call for fulfillment of the long-standing international obligation to achieve nuclear disarmament.


Experience proves that citizen engagement and collective pressure on governments can push national policies toward reducing nuclear threats worldwide. Physicists, especially in the United States, have had a significant influence on nuclear weapons policy since the start of the nuclear age. Yet today, this issue receives scant attention from the U.S. physics community broadly, reflecting the post-cold war waning of public concern about nuclear weapon dangers. A new generation of the physics community must become informed, engaged, and active as knowledgeable advocates on this pressing issue.

With the support of the American Physical Society and Carnegie Corporation, our project team of expert physicists has launched the Physicists Coalition for Nuclear Threat Reduction. APS startup support, through its Innovation Fund, continued to October 1, 2022. Beginning in October 2022, the Coalition began a partnership with the Arms Control Association. Our goal is to reach out to physicists in the United States and mobilize those interested in opportunities for nuclear threat reduction. We welcome physical scientists broadly, including those in engineering. Together we can be a powerful voice to inform Congress and other key stakeholders in policy making, including the public. To build a national network of physicist-advocates on this issue, we are sending experts in nuclear arms control issues to physics institutions across the country to deliver colloquia, recruit physicists to the coalition, and foster local and national advocacy. Advocacy takes many forms, including educating senators, representatives, and their staff at home and in Washington, writing articles for the public, and coordinating messaging with local action groups and national NGOs active in nuclear arms issues.
