Over the last quarter century, digital technologies have transformed the way we ways we communicate, the way we shop, the way we bank, and even the way we socialize and consume information. With these advancements have come a number of vulnerabilities that adversaries and malign actors have sought to exploit in the cyber age.

Joining The Debrief to help weigh the challenges and opportunities posed by cyberspace is Dr. Derek S. Reveron, professor and chair of the National Security Affairs Department and co-author, with John E. Savage, of Security in the Cyber Age: An Introduction to Policy and Technology (Cambridge University Press, 2023).

The Arctic encompasses not only the territory of eight countries, but also vital geological features and strategic waterways that have made the region an area of ecological concern and geopolitical contestation.

To help navigate these waters, The Debrief talks with Dr. Mary Thompson-Jones, a retired Senior Foreign Service Officer and professor and chair of Women in Diplomacy and National Security, who is the author of America in the Arctic: Foreign Policy and Competition in the Melting North (Columbia University Press, 2025).

Today, economics is more a part of the national security equation than it has ever been. Trade, science, technology, innovation, and supply chains – to name a few issues – intersect with national security with more depth, breadth, and frequency every year. As a consequence, U.S. economic agencies are increasingly called to the table to solve national security challenges.

To help understand these many connections and what economic security looks like in practice at the highest levels of decision-making, The Debrief spoke with Don Graves, who served as Deputy Secretary of the U.S. Department of Commerce from 2021-2025.
