The war in Ukraine takes another left turn as Russian President Vladimir Putin makes more explicit nuclear threats: this week, Tom Collina sits down with Jon Wolfsthal, senior advisor at Global Zero and author of the sub-stack newsletter BoomBoomBoom. They discuss Putin’s nuclear threats, the fine line the Biden Administration has to walk, and how to avoid further escalation.

On Early Warning, Alex Hall talks with Sara Haghdoosti, executive director of Win Without War. She discusses the nationwide protests in Iran over governmental restrictions on women’s dress, which erupted after Mahsa Amini died in police custody after being arrested by the morality police for allegedly breaking Iran’s policy on hijabs.
