President Barack Obama and Lt. Gen. Robert Caslen Jr., superintendent at the U.S. Military Academy, stand for the national anthem during a graduation and commissioning ceremony at the academy, Wednesday, May 28, 2014, in West Point, N.Y. In a broad defense of his foreign policy, the president declared that the U.S. remains the world's most indispensable nation, even after a "long season of war," but argued for restraint before embarking on more military adventures.
