NPR has an interview with the author of a book I'm tempted to order for a future class.
It's called The Brothers: John Foster Dulles, Allen Dulles, and Their Secret World War.
Its about two brothers - the Dulles' - who seem to have dominated the nature of American foreign policy for the couple decades following WWII. Their activities seem to have been allowed to go forward by the presidents of that era.
They had this tendency to overthrown democratically elected governments in places like Iran. The author suggests that many of the problems we face internationally are the result of an ongoing backlash against their actions.
Its an interesting inside look at how foreign policy was actually made during a 20-30 years period of American history.
