Great Decisions 2026: The Future of U.S. Global Leadership Keynote Series

Ruptured Alliances & the Risk of Nuclear Proliferation

with Heather Williams, Director, Project on Nuclear Issues and Senior Fellow, Defense and Security, CSIS, moderated by Rebecca Davis-Gibbons

April 2, 2026, 5:30-7:30 PM, 34 Bedford Street, Portland

What happens when America’s allies begin to doubt U.S. security commitments—could it trigger a new wave of nuclear proliferation? Heather Williams directs the Project on Nuclear Issues at the Center for Strategic and International Studies and serves on the Defense Science Board. A leading voice on arms control, deterrence, and nuclear risks, she has advised the U.S. government and the UK House of Lords on nuclear policy. Join us for a vital conversation on whether the global architecture that has prevented nuclear spread for decades can survive an era of great power rivalry.
