Stephen Wertheim: Realism and restraint in US foreign policy

This week, our guest is Stephen Wertheim, Senior Fellow in the American Statecraft Program at the Carnegie Endowment for International Peace. We discuss the origins of “isolationism,” historical hypotheticals, the United States’ relative interests in the Middle East, Europe and Asia, Ukraine and Taiwan, and an “America first” policy for the Democratic party, among other subjects.
