Inside the Hunt for Hidden Nuclear Weapons | Eliana Johns
Eliana Johns hunts for nuclear weapons. She’s a senior research associate at the Federation of American Scientists, where her team uses open-source intelligence — or OSINT — to uncover secrets about countries’ nuclear capabilities and intentions. In fact, much of what we know today about China’s nuclear arsenal comes from her colleagues’ work, which used commercial satellite imagery to reveal that China is undertaking a massive nuclear buildup — at a pace far exceeding publicly available estimates from U.S. intelligence agencies. In our conversation, Johns explains where OSINT has worked best and why greater transparency around nuclear weapons is essential for a more stable and peaceful world. We recorded this live at the Carnegie International Nuclear Policy Conference.

Who Will Be the Next UN Secretary-General?, With Richard Gowan | To Save Us From Hell
The race to succeed António Guterres is unofficially underway. His term as UN Secretary-General ends in December 2026, but the backroom jockeying has already begun. In this episode, Mark and Anjali are joined by Richard Gowan of the International Crisis Group to break down the early contenders, how shifting geopolitics could shake up the selection process, and the daunting mess the next Secretary-General is likely to inherit. But first, they react to Trump’s eyebrow-raising pick for UN Ambassador: recently fired National Security Advisor Mike Waltz.

In Memoriam: The Time Joseph Nye Told Me His Life Story
The legendary international relations scholar Joseph Nye passed away on May 7th at the age of 88. He’s best known, of course, for developing and advancing the idea of “soft power”—the ability to influence others and shape outcomes through attraction, persuasion, and cultural or ideological appeal rather than coercion or force. But over his singularly illustrious career, he authored hundreds of scholarly articles and dozens of books on international relations. To honor is legacy and memory, I wanted to share our conversation from way back in 2014. We began our conversation talking about Russia’s (then recent) annexation of Crimea and occupation Ukraine, and what it suggests about long held ideas in international relations theory. We then pivot to his personal story, including his childhood in New Jersey and how his entry into the world of international relations was as an Africanist—he wrote an award-winning thesis as a Rhodes Scholar on decolonization in East Africa. Of course, we also discussed at length how he came up with the idea of “soft power,” which, as he explains, stemmed from an “a-ha!” moment while sitting in his kitchen.

What We Know About Trump's Nuclear Policy | Alexandra Bell
In just the first four months of the Trump administration, several pillars of American foreign policy have been upended — USAID dismantled, most foreign aid frozen, and the rules-based international trade system thrown into disarray. Could nuclear policy be next? To find out, I spoke with Alexandra Bell, President and CEO of the Bulletin of the Atomic Scientists and a former senior State Department official on nuclear issues. She breaks down the key decisions facing the administration — and the risks tied to some of the options on the table, particularly around missile defense. We also unpack the state of nuclear diplomacy with Russia and China, and why forcing trilateral arms control talks is likely a dead end. This conversation is a clear-eyed look at the current state of play in Trump’s nuclear policy — and where it may be headed next. We recorded this live at the Carnegie International Nuclear Policy Conference. More conversations are coming soon. To catch them live, subscribe below or get the Substack app.

When Treaties Work: The Comprehensive Test Ban Treaty
The Comprehensive Test Ban Treaty, better known as the CTBT, expressly prohibits its signatories from testing nuclear weapons. It was opened for signature in 1996 and is now one of the most widely adopted treaties in the world. Since the Comprehensive Nuclear-Test-Ban Treaty was opened for signature in 1996, there have been ten nuclear tests conducted worldwide. These include two tests by India and two by Pakistan in 1998, and six tests by North Korea between 2006 and 2017 . This limited number of tests since 1996 stands in stark contrast to the more than 2,000 nuclear tests conducted in the preceding five decades, highlighting the CTBT's significant role in establishing a global norm against nuclear testing My guest today, Robert Floyd, is the Executive Secretary of the Comprehensive Test-Ban Treaty Organization, which—as the name suggests—is the international body responsible for monitoring and facilitating the implementation of this treaty. It does so, in part, through a sophisticated global monitoring system capable of detecting a nuclear test anywhere in the world. I sat down with Robert Floyd on the sidelines of the Carnegie International Nuclear Policy Conference in Washington, DC, earlier this month, where he explained why the CTBT has been so successful in constraining nuclear testing—and what challenges the treaty now faces amid a rapidly shifting geopolitical landscape. This episode is produced in partnership with Lex International Fund, a philanthropic fund dedicated to strengthening international law to solve global challenges. It is part of a series that demonstrates the impact of Treaties on state behavior that we are calling "when treaties work"
