The USA and Iran may remake the geopolitics of the Middle East with a successful outcome of a nuclear deal. Failure to reach a nuclear agreement between the USA and Iran will come with its own set of profound consequences. I speak with Alireza Nader of the Rand Corporation about the regional and global implications of both failure and success in reaching a nuclear deal with Iran. We discuss the potential shifting of alliances in the Middle East, how a detente between the USA and Iran may affect the conflict in Syria, and how Saudi Arabia may respond to a diplomatic breakthrough. Have a listen.
