America has often developed very impressive methods of waging war and protecting strategic interests, but all too often, its senior leaders are too optimistic about how much those methods can actually accomplish. The heart of U.S. national security challenges today is an ongoing erosion of American influence globally. What the U.S. now requires is a modification of older ideas in ways appropriate for the modern age. The works contained in this edited volume are signposts of a future that America still has time to choose wherein its efforts to safeguard its people and protect its interests can be remade and reforged in ways appropriate and successful in this era of dazzling technologies and enormous global change.
