Benjamin Wittes sat down with Mike O'Hanlon who writes on military affairs and foreign policy, and has been a senior fellow at the Brookings Institution for a long time. His latest book is "The Senkaku Paradox: Risking Great Power War Over Small Stakes." The title says it all. It's about the places in the world that are the potentially most explosive flashpoints over the least important U.S. interests. It's about the places in the world where we are treaty-bound to go to war to protect trivia. And, it's about thinking creatively about how to handle low-stakes questions in a high-stakes world.
