The Great Power coalition of the early 19th century succeeded in keeping the peace among the major states of England, France, Prussia, Russia, and Austria. For the last century and a half, however, no truly encompassing coalition has emerged, and in its absence the 20th century was plagued by world wars and peripheral conflicts.Only now, at the outset of the 21st century, is a new Great Power coalition possible. This book examines the prospect of a Great Power coalition that would be sustained by the development of "overlapping international clubs." The new set of Great Powers-the United States, Japan, the European Union, China, and Russia-can be increasingly bound together through a combination of status and economic incentives, international norms and regimes, and the emulation of national and regional "best practices."The construction of such a coalition presents special problems and opportunities for the United States. In the years ahead, America will need to adjust its policies to bring China and Russia into membership of such a group or see them progressively adopt recalcitrant and antagonistic attitudes toward world affairs.
