Like it or not, George W. Bush has launched a revolution in American foreign policy. He has redefined how America engages the world, shedding the constraints that friends, allies, and international institutions once imposed on its freedom of action. In America Unbound, Ivo Daalder and James Lindsay caution that the Bush revolution comes with serious risks-and, at some point, we may find that America's friends and allies will refuse to follow his lead, leaving the U.S. unable to achieve its goals. This edition has been extensively revised and updated to include major policy changes and developments since the book's original publication.
