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 econom incentives, international norms and regimes, and the emulation of national and regional best practices.
