I know a something about the works of Andrew Bacevich and Stephen Kinzer and hold them in highest regard. Andrew Bacevich is author and professor at Boston University. Stephen Kinzer is author of "The Brothers: John Foster Dulles, Allen Dulles and their Secret World War". Evan Thomas is author and professor of Journalism at Princeton University.

Boston Globe national security reporter Bryan Bender moderates.
