Is "Progressive Realism" the Future of US Foreign Policy?

The American foreign policy tradition has been recently dominated by just a few ideologies: neoconservatism of the Regan and George W. Bush eras and the liberal internationalism of the Clinton and Obama administrations.  Robert Wright, has helped to introduce and popularize a new kind of intellectual tradition to the public square called "Progressive Realism."  He explains some key principals of a progressive-realist foreign policy and how this ideology might be applied to some key foreign policy challenges, including competition with China and conflict in the middle east.  Guest:  Robert Wright is the author of several books, including  NonZero: The Logic of Human Destiny and runs a newsletter of the same name.
