The Doomsday Clock has just been set at 85 seconds to midnight, the closest it has ever been to symbolic human-caused Armageddon. It's no coincidence that this happened just a week before the last remaining nuclear arms control agreement between the United States and Russia — known as New START — expired February 5. Now, the landscape of nuclear arms control looks increasingly bleak. Is there any room for optimism? Communications Director Anna Schumann sat down with Alex Bell, President and CEO of the Bulletin of the Atomic Scientists (the people behind the famed Doomsday Clock) to discuss their decision to move the clock's hands closer to midnight, what the expiration of the New START agreement means for future of arms control and how YOU can help stop an arms race.

Just a note that as we hit publish Thursday on this episode we recorded Monday, Axios broke news that the United States and Russia are working on a draft plan to informally extend New START — a welcome development, if true. But is that enough to stave off a nuclear arms race? Listen and find out. https://www.axios.com/2026/02/05/new-start-arms-control-us-russia-extend

On August 6 and 9, 1945, the United States bombed Hiroshima and Nagasaki with the first nuclear weapons ever used against another country. In this special episode, Communications Director and Guest Host Anna Schumann takes a step back from the hard-hitting policy deep dives Nukes of Hazard is generally known for to speak with Sara Burkinshaw, whose grandmother survived the bombing of Hiroshima. Sara details the moment that made her realize why sharing her grandmother's story matters and what she believes compels young people to understand the dangers of nuclear weapons. For more on her grandmother's story, listen to our episode, "The Human Cost of the Hiroshima Bombing," with Sara's mother, Kathleen Burkinshaw.

Open-source intelligence (OSINT) and satellite imagery have changed the way civil organizations understand and evaluate nuclear arsenals and delivery systems — and the way governments interact with a changing balance of transparency and secrecy. Join us as we break down new developments in OSINT technology, how OSINT analysis can be used in nuclear weapons verification and the challenges ahead in regulating its use. Host Farah Sonde speaks to Decker Eveleth, Graduate Research Assistant at the James Martin Center for Nonproliferation Studies; Marcy R. Fowler, Research and Analysis Manager for Open Nuclear Network; Matt Korda, Senior Research Fellow for the Nuclear Information Project at the Federation of American Scientists; and Dave Schmerler, Senior Research Associate at the James Martin Center for Nonproliferation Studies.

The Russian invasion of Ukraine has brought us closer to nuclear escalation than ever in a post Cold War world. One major question hangs overhead: what if Ukraine had kept its nuclear arsenal after the USSR’s dissolution? Host Geoff Wilson speaks with Mariana Budjeryn, author of Inheriting the Bomb: The Collapse of the USSR and the Nuclear Disarmament of Ukraine, about how Ukraine made the brave decision to give up the bomb.

What happens when a new country is born with nuclear weapons already within its borders? What happens when the legacy of nuclear testing takes place almost entirely within communities of color? And how do the answers to these questions get knit together to form a national identity that refuses nuclear weapons, even in a world that seems to want to seek them out more than ever? Host Geoff Wilson talks with Togzhan Kassenova, Center board member and author of Atomic Steppe: How Kazakhstan Gave Up the Bomb, to break down these questions.

Battlefield nuclear weapons — also called tactical or nonstrategic nuclear weapons — are a continuing topic of conversation in the halls of Congress and inside the Pentagon following Russia's invasion of Ukraine. But what are they, are they necessary and why do we keep talking about them? Host Geoff Wilson talks with Jane Vaynman, Assistant Professor in Political Science at Temple University, to discuss their role in the U.S. nuclear arsenal, deterrence and more.

This year marks the 20th anniversary of the September 11th attacks, a day that changed the trajectory of world history in ways that we are still coming to terms with. In this special episode of Nukes of Hazard, host Geoff Wilson talks to the Center's Executive Director, former Congressman John Tierney about his experience in Congress post-9/11, his work to redress some of the worst policies that came out of these tragic events, and how we must reframe the way we think about national security going forward.
