President Barack Obama's Speech at the National Defense University on May 23, 2013
For over two centuries, the United States has been bound together by founding documents that defined who we are as Americans, and served as our compass through every type of change. Matters of war and peace are no different. Americans are deeply ambivalent about war, but having fought for our independence, we know that a price must be paid for freedom. From the Civil War, to our struggle against fascism, and through the long, twilight struggle of the Cold War, battlefields have changed, and technology has evolved. But our commitment to Constitutional principles has weathered every war, and every war has come to an end.

Too bad you don't watch videos Robert. This is quite a remarkable speech, especially towards the end.
