This is the third in a multi-part series of episodes examining the 20th anniversary of the U.S. invasion of Iraq, which began on March 20, 2003. The video version of this episode will air on C-SPAN 2's American History TV on April 1. Melvin Leffler, an eminent historian of U.S. foreign policy, joins Martin Di Caro in a conversation about Leffler's new book, "Confronting Saddam Hussein." The historian argues the Bush administration was influenced by fear, overconfidence in U.S. power, and hubris rather than outright dishonesty when it drove the country to war in 2003.
