The Best National Security Gossip

NO PRESS IN THE PRESS OFFICE: It’s not really a secret that this Pentagon doesn’t find much use for members of the press, even though the Secretary of Defense used to be one of them. In an exclusive, the Washington Post now reports that the Pentagon is barring members of the press from the press office. (We had to read that twice, too.) Traditionally, reporters have dropped by the office to ask questions - but not anymore. The official reason for the ban: speechwriters have moved into the space, and they access classified material, so no one without a security clearance can be there. So the message we’re taking away if, [...] More

State Secrets

What happens when artificial intelligence, climate disruption, geopolitical rivalry, and information warfare collide?

In this episode of the State Secrets Podcast, Cipher Brief CEO Suzanne Kelly sits down with retired Admiral James Stavridis and bestselling author and former Marine Eliot Ackerman to discuss their new novel, 2084—the final installment in their acclaimed trilogy that began with 2034 and 2054.

Drawing on decades of military, intelligence, and geopolitical experience, Stavridis and Ackerman explore a future shaped by climate-driven migration, AI-powered conflict, surveillance, shifting global power centers, and the growing competition for influence in the Arctic and beyond. They explain how fiction can serve as a strategic warning, helping readers imagine future crises before they become reality.

The conversation also examines the risks of cognitive warfare, autonomous weapons, U.S.-China tensions, democratic resilience, and why—despite the challenges ahead—the authors remain cautiously optimistic about humanity’s ability to navigate the century's biggest threats.

If you care about the future of national security, technology, and global stability, this is a conversation you won't want to miss.
