Michael Allen discusses Iran's new Supreme Leader with Jeffrey Feltman, a visiting fellow at the Brookings Institution and former UN Under-Secretary-General. Feltman examines the sudden rise of Mojtaba Khamenei following the death of his father, Ali Khamenei, and discusses the regime's internal cohesion despite widespread domestic opposition. He also explains Israeli military targeting strategies, the risk of a "race for the bomb," and the potential for significant regional escalation.
