Over ten years ago, most Arab countries in the Middle East cut ties with the Syrian government during the civil war and supported armed groups dedicated to the overthrow of the Bashar al-Assad regime. Meanwhile, Iran was Assad's key backer. 

But now, in the Spring of 2023 a big shift is underway. Saudi Arabia and Iran are taking steps towards rapprochement and Arab governments throughout the region are re-opening embassies in Damascus and re-establishing diplomatic relations with Syria.

Joining me to explain what is driving this regional re-alignment is Joshua Landis, director of the Center for Middle East Studies at the University of Oklahoma and the Mackey Chair. We kick off discussing how the outbreak of the Syrian civil war impacted regional diplomacy and why now we are seeing such profound changes in the the geopolitics of the Middle East.
