Less than two weeks into the American and Israeli bombardment of Iran, the war is both a success and a failure. Militarily, the campaign has effectively degraded the Islamic Republic’s warmaking capacities. But politically, thus far, it has only strengthened the regime’s cohesion.

President Trump may have hoped the elimination of the Islamic Republic’s longtime supreme leader, Ayatollah Ali Khamenei, would produce an Iranian Delcy Rodríguez—a pragmatic insider who would capitulate to American pressure—but it has instead spawned a budding Iranian Kim Jong Un. Mojtaba Khamenei, 56, will succeed his father, making the Islamic Republic a hereditary dictatorship poised to double down on ideology and repression.
