Since the 1960s, PSR has been dedicated to the global prevention of nuclear war. PSR is the United States affiliate of the International Physicians for the Prevention of Nuclear War (IPPNW), which in 1985 was awarded the Nobel Prize for Peace for our efforts to reduce the dangers posed by the development, production, testing, deployment and use of nuclear weapons. We believe that the worldwide proliferation of nuclear weapons poses an environmental and public health threat of almost unimaginable proportions and must be countered with broad and effective popular action.

PSR is directly involved in efforts to end continuing nuclear weapons testing and development, to take existing weapons off hair-trigger alert particularly in this era of Trump, to secure a global Comprehensive Test Ban Treaty while strengthening the Non-Proliferation Treaty, to demand remediation of nuclear facilities, to halt plans for a costly and destabilizing National Missile Defense System, and to work for the abolition of nuclear and all other weapons of mass destruction.

To carry-out this work locally, we are in coalition with other anti-nuclear organizations to stop research and development at the Lawrence Livermore National Laboratories (LLNL), specifically to prevent the implementation of costly plans to update our nuclear arsenal, which will take essential funds away from human needs.

We regularly write about and advocate on issues around nuclear arms and security. Please go here to stay informed!
