'Wisdom' from three former Secretaries of State

This week Uncommon Knowledge, brings us interview excerpts from three former secretaries of state including two Hoover fellows Henry Kissinger and Condoleezza Rice, and Robert McNamara. All three have influenced American foreign policy through the years and through different crises, and all three believe that the United States possesses a particular responsibility in the world. They discuss foreign policy, critical decisions that were made before and during wars, what we have learned from those decisions, and what we can do better.
