What Just Happened: Federalization of Law Enforcement in Washington DC
This week, the Trump administration took over command of the D.C. police department, and surged federal law enforcement officers and National Guard units into the city. While the United States has a long tradition of leaving most policing to state and local agencies, federal law enforcement has specific powers, and there are well-established limits on the use of military forces for domestic law enforcement, but the rules for DC are particular.In this episode, host David Aaron is joined by Carrie Cordero, General Counsel at the Center for a New American Security and former Counsel to the Assistant Attorney General for National Security and Senior Associate General Counsel at the Office of the Director of National Intelligence, and Donell Harvin, Visiting Fellow at the National Security Institute at George Mason University and former Chief of Homeland Security and Intelligence for the District of Columbia. Together, they unpack significant legal and policy considerations concerning the Executive Branch’s recent actions and the open questions still in play.Show Notes:Center for a New American Security, The 21st Century National Guard: Expanding Missions, Modernizing AuthoritiesJust Security’s Law Enforcement and National Security Archives"How to Truly Keep Washington, DC Safe: President Trump’s militarized approach undercuts what’s been working" by Donell Harvin

Ukraine’s Resistance to Russia’s Invasion: The Other Mobilization
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

Decoding Trump’s AI Playbook: The AI Action Plan and What Comes Next
Yesterday, the White House released its long-awaited AI Action Plan and signed three executive orders on AI, laying out the Trump administration’s strategy to secure what it calls “unquestioned and unchallenged” U.S. dominance across the entire AI tech stack. Framing AI as a global race for technological supremacy, the Plan envisions nothing short of an industrial revolution, an information revolution—and even a renaissance—all driven by AI. To achieve that vision, the Plan is centered around three pillars: innovation, infrastructure, and international diplomacy and security. It calls for upskilling the workforce, revising federal rules, building high-security data centers, and tightening export controls—all whilst removing what the administration views as regulatory obstacles to faster AI adoption.The plan also raises major questions. What’s the role of government in steering this technology responsibly? Are we building the right guardrails as we scale up? And what message is the U.S. sending to allies and adversaries as it charts a new course in AI policy?Show Notes: Sam Winter-Levy’s article, "Assessing the Trump Administration’s AI Action Plan" (July 25, 2025)Joshua Geltzer’s article “The Trump Administration’s AI Action Plan Is Coming.

What Just Happened: The Budget Bill and the Future of DHS and ICE
The massive budget bill that passed this month allocates tens of billions of dollars to the Department of Homeland Security (DHS), U.S. Immigration and Customs Enforcement (ICE), and Homeland Security Investigation (HSI). The influx of funding of that scope and size will significantly expand the role DHS and immigration enforcement agencies play in American life.What are the the institutional constraints on the FBI and law enforcement agencies compared to those on DHS and immigration enforcement? To help unpack what these differences might mean for achieving policy objectives while protecting civil liberties and providing political accountability, host David Aaron is joined by Steve Cash, who comes with a wealth of high-level experience in Congress and the executive branch and who most recently served as Senior Advisor to the Under Secretary of the Department of Homeland Security.

Trump’s Shift on Ukraine and Russia: A Conversation with Amb. Daniel Fried and Dara Massicot
President Donald Trump this week put weapons behind his growing irritation with Russian President Vladimir Putin’s intransigence on negotiations to end the war in Ukraine. Meeting at the White House with NATO Secretary-General Mark Rutte, President Trump announced that the United States will work with European allies in NATO to send advanced weapon systems, including Patriot missile batteries, to Ukraine. He also threatened tariffs and additional sanctions against Russia and countries that do business with it if it doesn’t ease its assault on Ukraine and make progress on stalled peace talks within 50 days. What impact is this policy shift likely to have on the war in Ukraine? Will the combination of military support for Ukraine and economic threats toward Russia succeed in forcing President Putin to the negotiating table, or could they spur further escalation? On this episode, host Viola Gienger is joined by Ambassador Daniel Fried and Dara Massicot to discuss Trump’s policy shift on Ukraine and its impact.Show Notes:The Just Security Podcast: A Ukrainian MP Takes Stock of the NATO Summit and the Prospects for Peace, with Ukrainian MP Oleksiy Goncharenko, Lauren Van Metre, and Viola Gienger.
