The nuclear age began in secrecy and scientific ambition. The story is familiar, but its implications have never left us. A bomb created in a moment of wartime urgency became the foundation of a global order defined by terror and deterrence. But what happens when that global order breaks down? Face-Off: Nuclear Anarchy is an 8-part series tracing the arc of nuclear danger from the Manhattan Project to the Cuban Missile Crisis to the abandonment of the New START treaty and the shattering of the nonproliferation order today. We take you behind the scenes of key moments and key places of the nuclear story to shed light upon the present. In each episode, Pulitzer-winning journalist Jane Perlez interviews leading participants in the nuclear conversation: David Sanger, Tong Zhao, Rose Gotemoeller, Alex Wellerstein and more. Plus, Matthew Bunn, of Harvard's Managing the Atom project, joins for a wrap-up segment to put everything in context.  We are living in a more crowded and unstable nuclear world—where proliferation spreads not through ideology or conquest, but through fear, hedging, and the collapse of confidence. Face-Off asks who will hold the line, and for how long?  Episodes out every Tuesday in October & November 2026.  This project is made possible by the Belfer Center at the Harvard Kennedy School and the Managing the Atom Project. Our special guest is Professor Matthew Bunn, Faculty Chair of the Managing the Atom Project (@matthew-bunn.bsky.social). Face-Off is produced and reported by Jane Perlez. Our production team is Nina Porzucki, Louise Morris, and Frank Zhou. Sound design and mixing by John Myers and Rowhome Productions.
