Jack Goldsmith sat down in Cambridge, Massachusetts, to have a conversation with former Secretary of Defense Ash Carter. They talked about Carter's time as head of the Pentagon, the challenges of conveying national security threats to the American public, the Obama administration's response to the rise of the Islamic State, offensive cyber operations, and the role of lawyers in defense policy. They also discussed Carter's new book, "Inside the Five-Sided Box: Lessons from a Lifetime of Leadership in the Pentagon." See acast.com/privacy for privacy and opt-out information.
