Take Action: Health Professionals Oppose Resumption of Nuclear Explosive Testing November 24, 2025

We write to you to ask for your help in opposing the recent announcement by President Trump to resume nuclear weapons testing in the United States. PSR, in solidarity with International Physicians for the Prevention of Nuclear War, issued a joint statement denouncing any suggestion of renewed explosive nuclear testing, reaffirming that nuclear weapons testing causes catastrophic human health consequences, and violates the global norm prohibiting nuclear explosive testing. 

President Trump’s instruction to restart testing of U.S. nuclear weapons on social media last month is a reckless step that threatens decades-long efforts to prevent nuclear escalation and global destabilization. As health professionals, we know that any detonation is not just a technical or geopolitical issue, but a public health catastrophe with intergenerational impacts. Renewed testing would break the global taboo that has held for decades, put populations in harm’s way, and would severely damage the credibility of international arms control. Now is the time to act not only for our country’s health, but for the world. Testing must remain an atrocity of the past.

We urge you to contact your Senators and Representatives immediately and demand that they:

1. Oppose any funding or authorization for renewed explosive nuclear weapons testing.
2. Back H.Res 5894, the RESTRAIN Act, introduced by Rep. Dina Titus, to explicitly prohibit any explosive nuclear testing and block funding for resumed testing.
3. Co-sponsor S.Res. 3090 preventing funding for nuclear testing in 2026. 
4. Support S.Res. 323, which urges the U.S. to lead a global effort to halt and reverse the nuclear arms race and maintain the existing de-facto testing moratorium. 
5. Co-sponsor H.Res. 317 and S.Res 323, which maintain a U.S. moratorium on nuclear testing and advance negotiations for nuclear disarmament. 

Your voice as a health professional and member of PSR is powerful. Policymakers must hear that the medical and public-health community will not stand by while the U.S. abandons its leadership on the global norm against nuclear testing.
