Since invading Ukraine, Russian President Vladmir Putin has relied on nuclear threats to deter Western intervention and signal his commitment to this war. Ploughshares Fund President Dr. Emma Belcher talks with Dr. Heather Williams, director of the Project on Nuclear Issues and a senior fellow in the International Security Program at the Center for Strategic and International Studies (CSIS). They discuss the role of nuclear deterrence in the war in Ukraine, whether the war has shifted the current thinking on deterrence theory, and possible pathways for arms control.

On Early Warning, Alex Hall recognizes Human Rights Day with Raeghn Draper, associate partner for mobilization & partnerships at Global Zero. They discuss the human costs of nuclear weapons and how the nuclear abolition movement can learn from other social justice movements.
