Aftermath of Israeli Airstrike In Gaza A Palestinian man rests amid debris at the site of an Israeli strike on a house in Gaza City, on July 30, 2026. The strike followed warnings to evacuate the area. Gaza remains subject to daily violence, with both the Israeli military and Hamas accusing one another of violating the truce in effect since October 10. The conflict has flattened swathes of the territory, displaced most of the population at least once, and left hundreds of thousands of people living in tents and temporary shelters.

The Best National Security Gossip

DON’T YOU HATE WHEN THAT HAPPENS? It used to be that embarrassing mistakes that popped up during public presentations just kinda got forgotten about, eventually. But not in a world full of social media. Our case in point: a presentation by the State Department at a global conference on AIDS in Brazil this week turned rather awkward when a slide showing a map of Africa that was included in a State Department presentation listed highlighted countries that were all mislabeled. (Looks like someone wasn’t paying attention in geography class.) If we’re honest, we’ve all mislabeled a country or two on a map but conference [...] 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.
