For tonight's Conversations With Great Minds - I'm joined by one of America's leading investigative journalists. The winner of the 2012 Martha Gellhorn Prize for Journalism - Gareth Porter is known for reporting that cuts through mainstream narratives and tells largely unknown truths about American foreign policy. A Vietnam specialist by training with a Phd in Southeast Asian studies - he worked as the Saigon Bureau Chief for Dispatch News Service during the height of the Vietnam War and later served as the co-director of the Indochina Resource Center right here in D.C. Since 2006 - Gareth has been hard at work uncovering the true story behind the US-Iranian nuclear standoff - which he has writtten about in his fascinating new book - "Manufactured Crisis: The Untold Story of the Iran Nuclear Scare."
