American power today is without historical precedent, dominating the world system. No other nation has enjoyed such formidable advantages in military, economic, technological, cultural, and political capabilities. How stable is this unipolar American order? Will the age-old dynamic of the balance of power reemerge as the other great powers rise up to challenge American preeminence? America Unrivaled examines these questions. The experts in this volume contend that full-scale balancing in this new world order has not yet occurred. They ask if a backlash against American dominance is just around the corner, or if characteristics of the current situation alter or eliminate the entire logic of power balancing.American power poses threats, as do the likely responses to that power, the experts argue in America Unrivaled. The definition of these threats is critical to understanding future political trends and learning whether an original (and stable) world system has already come into existence. Most of the contributors agree that novel features of the American hegemony and the wider global order make an automatic return to a traditional balance of power order unlikely.
