In this episode, Robert and Robinson discuss why the Iran war has become an escalation trap for Donald Trump, the United States, and Israel. More particularly, they talk about Pape’s argument that the war has strengthened Iran while weakening America’s regional position, Iran’s leverage over the Strait of Hormuz, and how cheap drones and precision weapons are changing the balance of military power. They also discuss how the 2026 midterms could prolong escalation, the limits of predicting war, how AI could make political assassinations easier, and the risks of weapons operating without human oversight. Robert’s latest book is Our Own Worst Enemies: America in the Age of Violent Populism (The New Press, 2026).
