Lt. Col. John Nagl (US Army Ret.) is a military strategist whose new book, Knife Fights - A Memoir of Modern War in Theory and Practice, compares the drawing board and the battlefield. His previous book, Learning to Eat Soup with a Knife, has become the bible of counterinsurgency. Along with Gen. David Petraeus, he rewrote Army doctrine, and as a commander and then a professor, and now a headmaster, has shaped thousands of lives and tempered a generation of leaders. He is complex, he is fascinating, and he's just like you and me. Give him a listen.
