Preventing Nuclear War

For more than 70 years, the world has faced the very real threat of nuclear war.

And now with Putin's ongoing invasion of Ukraine, we are closer to that threat than before. UCS experts are closely tracking developments in Ukraine, working to ensure a science-based response and continuing to educate the Biden Administration about enacting policy changes and preserving its commitment to diplomacy so that the United States can be a leader in reducing the nuclear threat.

US nuclear policy remains rooted in the Cold War, increasing the risk that nuclear weapons could be used again.

It doesn’t have to be this way. With the right policy changes and a commitment to diplomacy, the United States can be a leader in reducing the nuclear threat—and you can help.

1. Engaging & educating the Biden administration,
2. Pressuring Congress to support change,
3. Holding the White House accountable through independent research and analysis,
4. Increasing public demand for changing nuclear weapon policies.
