"Gary Hart has long been one of the nation's foremost experts on national security, combining a deep knowledge of national security policy with first-hand experience of the political realities that influence how America safeguards itself and its interests. In his new book, Hart outlines, in clear, simple prose, the fundamental changes with which America must grapple when confronting a terrorist threat that has no state and no geographic homebase and thus offers no genuine target for the world's largest and most sophisticated military force."--P.
