Today's episode is produced in partnership with the Global Challenges Foundation. The foundation is dedicated to raising awareness of global catastrophic risks and strengthening global governance to address them. The Global Challenges Foundation's 2026 Global Catastrophic Risks report outlines five of the biggest risks facing humanity today, including an asteroid colliding with earth, the topic of this episode. You can find the report at globalchallenges.org/gcr-2026. To discuss the potential consequences of an asteroid impact, and how we have built a system of planetary defense to guard against this risk, I am joined by Romana Kofler, program management officer at the United Nations Office for Outer Space Affairs, and Anja Olin-Pape, head of programs at the Global Challenges Foundation. We kick off by discussing the ways in which an asteroid impact could disrupt life on Earth and cause mass destruction, before turning to a longer conversation about how international cooperation and global governance have given us the tools to prevent an asteroid impact — and the catastrophe that would entail.

The civil war in Sudan is now entering its fourth year. Full-scale conflict broke out in April 2023 following a failed democratic transition, when two powerful rival militaries, the Rapid Support Forces and the Sudanese Armed Forces, fought each other for control of the country. Caught in the middle were the Sudanese people, 14 million of whom have been displaced, making this the largest humanitarian crisis in the world by the numbers. Four years on, I wanted to learn more about the state of the civil war today, including how the Iran conflict is impacting Sudan. Many of the same outside forces in the Gulf that have backed various sides in Sudan's civil war are now themselves under attack. Further, as we explored in a previous episode, rising fertilizer prices are hitting crisis-prone places like Sudan particularly hard. My guest today is Sudan analyst Dallia Mohamed. We kick off our conversation by discussing the current trends in this war. She then explains how the Iran war is impacting Sudan's own conflict before we have a longer discussion about what can break this cycle of violence.

The Security Council is weighing yet another U.S.-backed resolution on the Strait of Hormuz that is probably doomed from the start. In this first segment of To Save Us From Hell, Anjali and Mark explain the flawed logic behind this latest effort to return the Strait to its status quo ante bellum. Then, Mark discusses what he learned covering the Nuclear Non-Proliferation Treaty Review Conference, underway at the UN — the major multilateral nuclear security gathering that happens every five years. Finally, Anjali and Mark consider the latest American effort to withhold money it already owes to the UN — threatening to plunge the organization into an even deeper fiscal crisis.

Houston at Large is a show produced by Rice University Master of Global Affairs students Luisa Tolda and Dante Garcia. The podcast aims to analyze Houston's role in international matters such as immigration, energy, and trade. The first episode of this series, presented today, features Dr. Tony Payan, Director of the Claudio X. González Center for the U.S. and Mexico at the Baker Institute at Rice University. In this episode, Dr. Payan discusses a range of issues, including how immigration impacts Houston and how current events, such as the Iran conflict, have affected Houston, a major energy hub. Congratulations to these students for bringing this podcast to life! Now here are Luisa Tolda and Dante Garicia.

Days of Love and Rage: A Story of Ordinary People Forging a Revolution by Anand Gopal takes readers to the Syrian city of Manbij before, during, and after the civil war. Against all odds, the people of Manbij evicted the Assad regime from the city and built a democracy from scratch, even as civil war raged throughout the country. This experiment in self-rule was complex and inspiring, but ultimately short-lived: the Islamic State eventually took over the city, destroying the trappings of democracy that the women and men of Manbij had built for themselves. Days of Love and Rage is one of the best books I have read in a very long time, and I was thrilled to speak with Anand Gopal about Manbij's democratic experiment and what it means for societies facing state collapse.

The Nuclear Non-Proliferation Treaty is the most important and impactful global agreement on nuclear weapons. 191 counties have joined the NPT since it entered into force in 1970, with just a few notable exceptions, including India, Pakistan, Israel and South Sudan. The NPT has three essential pillars: countries that do not have nuclear weapons cannot acquire them; countries that do have nuclear weapons need to work towards disarmament; and countries should have the ability to access civilian nuclear technologies, under proper safeguards. Every five years, the parties to the NPT come together for what is known as a Review Conference in which they assess progress towards these three pillars and discuss ways to enhance the treaty. The NPT RevCon, as it's known, is one the major multilateral conference on nuclear security, and it is taking place at UN from April 27 to May 22. Joining me to discuss the significance of this NPT Review Conference is Kelsey Davenport, Director for Nonproliferation Policy at the Arms Control Association. We kick off with a discussion of the NPT itself, and it's impact over the decades and then have a long conversation about the key storylines, diplomatic intrigues and key policy debates that will unfold over the next three weeks at the UN. Consider this episode your curtain-raiser for the most important global gathering on nuclear security of the half-decade. A few notes. This episode is produced in partnership with Ploughshares, a foundation committed to reducing and ultimately eliminating nuclear threats. I'll have a follow up episode at the end of conference that discusses what exactly happened during the NPT RevCon. Also, I'll be attending much of the RevCon in person. I'll be serving as something akin to a "pool reporter," covering this conference in support of dozens of international journalists who report on nuclear security issues and feeding them news and insights from the confab. This project is backed by the Stanley Center for Peace and Security Developing Story Project, an initiative to support, strengthen, and sustain reporting on nuclear weapons and related issues. I'm looking forward to this. If you are around the UN, say hi.

On Tuesday and Wednesday this week, the four candidates for UN Secretary-General made their case at the UN General Assembly. Across twelve hours spanning two days, they took questions from UN member states and civil society groups eager to learn more about their priorities, proclivities, and leadership styles should they become the next UN Secretary-General on January 1, 2027. It was a marathon — and my To Save Us From Hell co-host Anjali Dayal and I watched it all! In today's episode, we tell you what we learned. To kick things off, we explain how the process for selecting a UN Secretary-General works — and how these hearings fit into it. We then break down what we heard from each of the candidates: Michelle Bachelet, Rafael Grossi, Rebeca Grynspan, and Macky Sall, bringing you the key highlights and takeaways. Consider this your curtain-raiser for a year of public campaigning and backroom dealmaking that will result in the selection of the next UN Secretary-General in the coming months.

The closure of the Strait of Hormuz is causing a surge in food prices around the world — particularly in places already in the midst of a humanitarian crisis. And it's about to get worse. This is the planting season for much of Africa and Asia, and fertilizer shortages mean that farmers are cutting back. Come this fall, crop yields will be reduced. One of the epicenters of this trend is Sudan, which, after three years of civil war, is the site of the world's largest humanitarian emergency. This is where I caught up with my interview guest, Kate Philipps-Barrasso, Vice President for Policy and Advocacy at Mercy Corps, a large international humanitarian relief organization. She spoke with me from Port Sudan, on the Red Sea, where she describes the immediate impact that the war in Iran has had on access to food and water. Mercy Corps recently released a report showing how fuel, fertilizer, and shipping disruptions have affected Somalia, Sudan, Pakistan, Ethiopia, and Myanmar, including the kinds of decisions farmers are making right now. The war in Iran's impact on global food prices has thus far been on the periphery of commentary about the conflict — but as this conversation shows, there is great urgency in understanding the cascading humanitarian consequences that are already unfolding.

Today's episode was recorded live at Lewis & Clark College in Portland, Oregon, for the annual Lewis & Clark International Affairs Symposium. The theme of this year's symposium was Crumbling Pillars: The Age of Authoritarianism. For this live episode, I speak with Lewis & Clark professor Kyle Lascurettes about how democratic backsliding and authoritarian resilience are impacting the United Nations and other international institutions. Kyle Lascurettes and I speak for about 25 minutes before a really interesting question-and-answer session with students. A huge thank you to the students for both their great questions and for organizing the whole thing. This was the 64th annual Lewis & Clark International Affairs Symposium, which is entirely student-run. I had a great time meeting many of the students and spending the day on this gorgeous campus.

As I am recording this on Friday, April 10, JD Vance is en route to Islamabad, Pakistan, for negotiations over a ceasefire announced on April 7. This ceasefire is shaky at best. It is clear that there was never a common understanding between Iran and the United States about what might be included in a ceasefire, but American and Iranian delegations are headed to Islamabad to discuss these details. My view is that this will likely be a long and drawn-out process with limited chances for meaningful progress in the near term. Still, the level of violence in the region is reduced from what it was before the ceasefire, and that is a good thing. There has been some reporting that China played a backroom role in helping convince Iran to come to the negotiating table, which I find interesting given the wide range of views among the Chinese foreign policy elite about how Beijing should approach this conflict. My guest today, Jacob Mardell, is Lead Analyst at Sinification, a Substack that tracks these very debates in Chinese foreign policy. He scours Chinese publications, blogs, and official statements to help the rest of us get a pulse on foreign policy debates in China. We have a long conversation about the contours of Chinese thinking about the war in Iran and the broader Middle East, including whether China might be willing or able to step in as a credible mediator, as well as the risks and opportunities China sees if the U.S. gets bogged down in another war in the Middle East.
