International law professors Chiara Giorgetti, Milena Sterio, and Rebecca Hamilton join Just Security’s Managing Editor, Megan Corrarino, to discuss takeaways from the American Branch of the International Law Association (ABILA)’s Oct. 23-25 International Law Weekend. 

In this special episode co-produced with ABILA’s International Law Chats podcast, which Giorgetti and Sterio co-host along with Alison Macdonald KC, the guests — each of whom also participated in International Law Weekend — discuss the weekend’s theme, “Crisis as Catalyst on International Law”; takeaways from panels on topics ranging from the proposed Crimes against Humanity Treaty to international environmental law and more; and how international lawyers and law students might think about their role in the present moment.

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.

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.

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.

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.

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.

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, and Mark Nevitt, associate professor of law at Emory University and former Distinguished Military Professor at the U.S. Naval Academy and a member of the Just Security editorial board.

Just Security Podcast: What Just Happened - Federalization of Law Enforcement in Washington DC with David Aaron, Carrie Cordero, and Donell Harvin

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.
