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.

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.

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?

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.

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.

In a picturesque valley in the mountains of eastern Bosnia, thousands of white gravestones bear witness to a mass atrocity that still struggles for a place in Europe’s conscience. Nearly 8,400 names are etched into a stone memorial, a stark reminder of the Srebrenica Genocide committed by Bosnian Serb forces against Bosnian Muslims in July 1995 – 30 years ago this year. And yet, too many political leaders and others continue denying the scale and scope of the travesty that unfolded there.

What has the world learned about genocide denial since Srebrenica? How has that denial echoed persistent efforts to negate or diminish the Holocaust? And how does denial and the politics around it tie into efforts to prevent a repeat elsewhere in the world?

Viola Gienger, Washington Senior Editor at Just Security is joined by Sead Turcalo, Professor of Security Studies at the University of Sarajevo and author of Thirty Years After the Srebrenica Genocide: Remembrance and the Global Fight Against Denial, published in Just Security; Velma Saric, founder and president of the Post-Conflict Research Center in Sarajevo; and Jacqueline Geis, Senior Director at the consulting firm Strategy for Humanity and a Research Fellow at the Human Rights Center at the University of California Berkeley School of Law

Today, the European Court of Human Rights (ECHR) delivered its highly anticipated judgement in the case of Ukraine and the Netherlands v. Russia–a watershed moment in international human rights law.

Iran’s nuclear program has long been a source of international tension. Early in U.S. President Donald Trump’s second term, hopes for a diplomatic resolution resurfaced—until June, when Israel launched strikes on Iranian nuclear and military sites. Days later, the United States joined the conflict, bombing three sites within Iran. Iran retaliated with missile attacks in Israel and a U.S. base in Qatar, and suspended cooperation with nuclear inspectors.

With both Washington and Tehran signaling interest in returning to talks despite the violence, what are the prospects for diplomacy now? To discuss where things stand and what a path forward might look like, Just Security’s co-editor-in-chief Tess Bridgeman is joined by Richard Nephew, a leading expert on Iran’s nuclear program and former Deputy Special Envoy for Iran.

The leaders of NATO, the North Atlantic Treaty Alliance, just finished their annual Summit in The Hague in The Netherlands, as Ukraine continues its existential fight against Russia’s full-scale invasion that began more than three years ago. That invasion, preceded six years earlier by the capture of Crimea and parts of eastern Ukraine, set off the biggest war in Europe since World War II. 

How do Ukrainian leaders see the outcome of the NATO Summit? What are the prospects for negotiations, and how are Ukrainians faring in the meantime? And what about relations between Ukraine and the United States under this new administration in Washington? And with its European partners? 

Washington Senior Editor Viola Gienger and guest host Lauren Van Metre spoke with Ukrainian MP Oleksiy Goncharenko to answer some of these crucial questions.

Over the past several days, the Trump administration has taken increasingly drastic steps in response to protest activity and unrest in Los Angeles — including federalizing 4,000 National Guard troops and sending hundreds of Marines, against the objections of California’s state and local leadership. 

As events unfold on the ground in LA, and in the lead-up to further anticipated protests this weekend, Just Security and the Reiss Center on Law and Security hosted a YouTube Live event to examine the pressing legal and policy issues at stake.
