This week on Babel, Jon talks with Sen. Chris Murphy, chair of the Senate Foreign Relations Subcommittee on the Near East, South Asia, Central Asia, and Counterterrorism. They discuss the U.S. relationship with Gulf allies, regional proxy battles with Iran, investing in Lebanon and Tunisia, and how worried policymakers should be about China's growing engagement with the Middle East. Then, Jon, Will Todman, and Caleb Harper discuss what a policy of greater U.S. restraint in the Middle East might look like and what impacts it might have.
