GREAT podcast. I listened to it several times:
Lawrence Wright spent five years researching the history of the events leading to the destruction of the World Trade Center Towers in New York City.
His book about the subject, The Looming Tower won the 2007 Lionel Gelber Prize, and the 2007 Pulitzer Prize. In this public lecture, Wright analyses the forces that created Al-Qaeda, and adds to our understanding of what we must do to fight them.
