A diverse panel, including retired general and former presidential candidate Wesley Clark, debates the proper size, cost, and missions for the United States Armed Forces in the 21st century. Some argue we spend far too much on preparing for and waging war while others see a gathering storm of global dangers requiring a buildup of the American military. Guests: Nora Bensahel, scholar at the School of International Service at American University, General Wesley Clark, former Supreme Allied Commander in Europe , Justin Johnson, defense budget analyst at the Heritage Foundation, Christopher Preble, Vice President for Defense and Foreign Policy Studies at the Cato Institute.
