Command Post: Should The U.S. Military Be the World's Cop?

Following World War II, perhaps it was inevitable that the U.S. military would be consigned to walking beats around the world like a neighborhood cop -- from Europe to Asia -- especially as the Cold War heated up. But now that the Cold War has been over for a generation, does it still fall to the U.S. to patrol the world's hotspots -- especially when that means that other, just as wealthy nations, might be getting a free ride? Your Battleland trooper debates the topic with John Nagl of the Center for a New American Security, along with Nora Bensahel, a military strategist now at CNAS, and retired Army lieutenant general Dave Barno.
