The Just Security Podcast

Since early September, President Donald Trump has ordered a series of U.S. military strikes on vessels in the Caribbean Sea the administration claims are linked to drug trafficking groups, leaving 32 people dead. One recent strike left two survivors, briefly detained by the U.S. military, and now reportedly repatriated to Colombia and Ecuador. The latest strike was reported by the Trump administration to have targeted suspected drug traffickers affiliated with a Colombian rebel group. The White House continues to defend the killings as part of a so-called war on “narco-terrorists,” while legal experts have resoundingly rejected the administration’s claims to wartime authorities.Tess Bridgeman is joined by Rebecca Ingber and Brian Finucane to assess the latest strikes, the brief detention of two survivors, where the campaign may be headed, and what it signals for executive power, accountability, and oversight moving forward.Show Notes:Tess Bridgeman, Brian Finucane, Rebecca Ingber, The Just Security Podcast: Murder on the High Seas Part II What We Know About the U.S. Vessel Strikes One Month In (October 7, 2025, also available on YouTube)Tess Bridgeman, Brian Finucane, Rebecca Ingber, The Just Security Podcast: Murder on the High Seas?

Since early September, President Trump has ordered the U.S. military to conduct multiple lethal strikes on boats in the Caribbean Sea suspected of drug trafficking, resulting in at least 21 deaths. What do we actually know about the people killed and the vessels targeted? What legal justification is the administration putting forward for the killings— and is it viable? Is there anything to stop the President from making further “terrorist” designations, of citizens or non-citizens, and ordering the military to kill those he designates, including within the United States? What checks exist — from Congress, courts, or within the executive branch itself — on the president’s claimed authority to order killings in these circumstances? On this episode of the Just Security Podcast, cross-hosted with the Reiss Center on Law and Security, host Tess Bridgeman and co-host Rachel Goldbrenner are joined by experts Rebecca Ingber and Brian Finucane to analyze the facts, the law, and the broader implications of this military campaign in the Caribbean.Show Notes: This is a joint podcast of Just Security and NYU Law School’s Reiss Center on Law and Security.Executive branch reporting on the vessel strikes, on Tren de Aragua, and related resources:48-Hour Report pursuant to the War Powers Resolution (September 4, 2025) (Note: For a living resource containing this and all other publicly available reports submitted pursuant to the War Powers Resolution since its enactment in 1973, see NYU Law’s Reiss Center on Law and Security’s War Powers Resolution Reporting Project)Notice to Congress Under 50 U.S.C. §1543a (Section 1230 of the FY 2024 National Defense Authorization Act) (undated, made public October 2, 2025)National Intelligence Council, Venezuela: Examining Regime Ties to Tren de Aragua (April 7, 2025)Listeners may also be interested in Just Security‘s Collection: U.S. Lethal Strikes on Suspected Drug Traffickers (updated, Oct. 3, 2025), including:Mary B.

The Cybersecurity Information Sharing Act (CISA) of 2015 is set to expire at the end of this month on September 30, 2025. The Act removes barriers to companies sharing information about cyber threats, addressing privacy concerns and requires the federal government to share threat information. Many consider CISA one of the foundations of U.S. cybersecurity efforts.   As Congress considers whether or not to reauthorize CISA, former Deputy Assistant Director of the FBI cyber division, Cynthia Kaiser, joins David Aaron to discuss the importance of the legislation and highlight the risks of failing to reauthorize it. Show Note: “The Next Cyber Breach Will Not Wait: Why Congress Must Reauthorize CISA 2015” by Simin Kargar for Just Security  Just Security’s CISA coverage Just Security's Cybersecurity coverage

Last week, Senator Elissa Slotkin (D-MI) unveiled a new “national security war plan,” centered on reviving the middle class, winning the global tech race, and rethinking how Americans are protected in an era of shifting threats and changing geopolitical realities. Senator Slotkin joins Just Security’s editors-in-chief Ryan Goodman and Tess Bridgeman to discuss the relationship between economic security and national security, the tools Congress should use to defend against threats to our democracy, the role for congressional oversight in domestic use of the military and in the recent military attack on a suspected drug smuggling vessel in the Caribbean, how the United States should engage with China in an era of increasing competition and cooperation, and a range of other national security and foreign policy priorities.Show Notes:  Senator Elissa Slotkin’s launch of her new vision for American national security and foreign policy at the Council on Foreign Relations.   Just Security’s AI and Emerging Technology Archive Just Security’s Congress Archive

Last week, the United States carried out an unprecedented strike against a vessel suspected of narcotics trafficking in the Caribbean, destroying the vessel and reportedly killing 11 people on board. This action raises highly concerning questions about the process followed within the U.S. government: how and by whom was the strike authorized?  Why was it carried out by U.S. armed forces? And what kind of accountability or pushback might we see from Congress, in courts, or within the government itself?Rebecca Ingber and Brian Finucane join Tess Bridgeman to unpack the attack, the limited justifications the administration has put forward to date, and what to expect from here. Show Notes: Legal Issues Raised by Lethal U.S. Military Attack in the Caribbean by Brian FinucaneLabels, Not Law, to Justify Lethal Force: Venezuela Boat Strike by Mark Nevitt

Ukraine’s response to the 2022 full-scale Russian invasion has been defined by extraordinary civilian mobilization. As millions of Ukrainians face the devastation of their homes, schools, and communities, volunteers—especially women—have stepped up in unprecedented ways to support the nation’s survival. In this episode, host Viola Gienger is joined by Lauren Van Metre, President and CEO of Women in International Security (WIIS) and a non-resident Senior Fellow at the Atlantic Council’s Eurasia Center, and  Ella Lamakh, founder of the Kyiv-based Democracy Development Center, to discuss how Ukraine’s women in frontline communities have stepped up to lead the local response. The episode also features the voices of three of the women in Ella’s network who are serving their frontline communities with humanitarian aid, organizing, and in one case, as a military administrator. Special thanks to those community leaders – Valentyna Holovata, Yuliia Porhenko, and Tetiana (who asked to use only her first name for security purposes), and to Dmytro Lysak for translation.Show Notes:  Voices from the Frontlines of Democracy in Ukraine: Supporting and Protecting Civil Society by Lauren Van MetreElla Lamakh’s Democracy Development CenterJust Security’s Russia-Ukraine War Archive
