This week on Babel, Jon Alterman speaks with Ali Vaez of the International Crisis Group. They talk about the Saudi-Iranian agreement to resume diplomatic ties, how it fits into Iran’s wider foreign policy strategy around the region, and the prospects for a broader détente between Iran and its Arab neighbors in the Gulf. Vaez suggests that a regional nuclear agreement between Iran and Arab states in the Gulf might be a more viable path forward than an agreement between Iran and the West. Then, Jon continues the conversation with Natasha Hall and Caleb Harper, discussing what this all means for U.S. policy toward Iran and in the rest of the region.  Ali Vaez, “The Long Twilight of the Islamic Republic,” Foreign Affairs, February 2, 2023.  Jon Alterman, "Saudi Arabia Steps Out," CSIS, March 23, 2023.
