It is time for fresh thinking about America's place in the world and the meaning of national security.

U.S. Army veteran and historian Andrew Bacevich, who is currently the president of the Quincy Institute for Responsible Statecraft, says it is long past time to question the fundamental assumptions underlying "American exceptionalism."
