This episode, we’re joined by Dr. Ash Carter, who just published "Inside the Five-Sided Box: Lessons from a Lifetime of Leadership in the Pentagon." He first started working at the Pentagon in 1981, and wound up playing an unlikely role in the so-called “Star Wars” missile defense program during the Reagan administration. Nowadays, he works at Harvard where he directs the Belfer Center for Science and International Affairs at the Kennedy School. Carter sat down with Defense One to talk about past wars, future wars, the importance of friends, America’s youth, China, what it takes to succeed in the Pentagon, how not to waste a $750 billion-dollar defense budget — and even theoretical physics. (The discussion begins at the 1:48 mark.)
