Transforming the Military How will the United States defend itself against the unknown, the unseen, and the unexpected? One way is by exploiting new technologies to develop a flexible arsenal: reduced nuclear forces, advanced conventional capabilities, and a range of defenses against missile, space, and computer attacks. Yet all the high-tech weapons in the world will not defend the country unless the Pentagon and the armed forces change the way they train, fight, and think. Americans and their military must accept changing coalitions, understand the need for pre-emptive offense, and prepare for a new kind of war that may increasingly be waged with non-military means. Now is precisely the time to begin making these changes; September a is all the proof we need.
