The Best National Security Gossip

CELL-YA LATER: “Loose lips sink ships” just got a 21st-century update. Some U.S. troops deployed in the Middle East, particularly in Jordan, could soon be ordered to surrender their personal cell phones, sources tell Reuters, amid growing concern that videos and photos posted online are handing Iran free battle damage assessments. CENTCOM commander Adm. Brad Cooper expressed concern to his troops in a July 28 letter. He was troubled by footage, including a clip shot on Meta smart glasses during an Iranian strike on Jordan's Muwaffaq Salti Air Base, that would help Tehran learn exactly how successful its strikes were, and [...] More

State Secrets

Recorded on location in Kyiv, Rear Admiral (Ret.) Mark Montgomery joins Suzanne Kelly for a timely State Secrets conversation on how Ukraine is reshaping the future of warfare.

Editor's Note: We caught up with Rear Admiral (Ret.) Mark Montgomery in Kyiv just as President Zelensky announced the firing of former Defense Minister Mykhailo Fedorov, prompting a wave of protests. Since this interview was recorded, additional developments - including changes in Ukraine's military leadership - have overtaken parts of that discussion. The strategic insights on Ukraine's battlefield innovation, however, remain as relevant as ever.

From Ukraine's increasingly effective long-range drone campaign against Russia's military infrastructure to the growing strain on Kyiv's air defenses, Montgomery explains why this war is becoming the world's most important laboratory for military innovation. He also shares firsthand observations from his latest trip to Ukraine - including conversations with commanders on the front lines - and discusses what the U.S., NATO, and Taiwan should be learning before the next major conflict.
