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,...

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...

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 gove...

The Trump administration’s unprecedented federalization of policing in Washington, D.C. raises significant legal and policy questions about the Executive Branch’s power over the Metropolitan Police Department and the use of National Guard forces from D.C. and other states, among other pressing topics. To break down the latest developments, host David Aaron is joined by Brian Netter, Legal Director at Democracy Forward and former Deputy Assistant Attorney General at the Department of Justice, ...

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 Ca...

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 ...

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 ...

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 enforce...

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...

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. Wha...

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. In this episode, Just Security Executive Editor and professor at American University Washington College of Law Rebecca Hamilton, and Just Security editorial board member and professor of International Law at the Fletcher School of Law & Diplomacy Tom Dannenbaum join Just Security co-edit...

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 signalin...

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 negotiatio...

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 e...

In recent years, the United States has sustained some of the most severe cyber threats in recent history– from the Russian-government directed hack SolarWinds to China’s prepositioning in U.S. critical infrastructure for future sabotage attacks through groups like Volt Typhoon. The Cybersecurity Infrastructure Security Agency (CISA) is responsible for responding to, and protecting against these attacks. How do leaders steer through cyber crises, build trust, and chart a path forward?&n...

For nearly 70 years, the DOJ’s Civil Rights Division led efforts to protect voting rights and fight racial discrimination at the polls. But in January 2025, DOJ political appointees froze all new civil rights cases and dismissed every major pending voting rights lawsuit—prompting most career attorneys to leave the Division. With federal challenges to restrictive voting laws now dropped in several states, the fight for voting rights falls to individual voters and advocacy groups, raising...

The State Department has released a reorganization plan that would usher in significant changes to the way the United States conducts its diplomacy and foreign assistance, at a time of considerable geopolitical change. Proposals by the Trump administration include eliminating or restructuring a number of the Department’s longstanding functions, dissolving and/or folding USAID into State, and imposing large budget and staffing cuts. Debates over how to structure and optimize the State De...

As the Supreme Court holds oral arguments on Thursday, May 15, Kristin A. Collins, Gerald Neuman and Rachel E. Rosenbloom argue that Executive Order 14160, which denies birthright citizenship to any child born in the United States who does not have at least one parent who is a U.S. citizen or lawful permanent resident, clearly violates the birthright citizenship federal statute. They note the statute has not received as much public attention, as they discuss the 1940s and 1950s legislat...
