"The international system of the twenty-first century will be marked by a seeming contradiction: on the one hand, fragmentation; on the other, growing globalization. On the level of the relations among states, the new order will be more like the European state system of the eighteenth and nineteenth centuries than the rigid patterns of the Cold War. It will contain at least six major powers—the United States, Europe, China, Japan, Russia, and probably India—as well as a multiplicity of medium-sized and smaller countries. At the same time, international relations have become truly global for the first time. Communications are instantaneous; the world economy operates on all continents simultaneously. A whole set of issues has surfaced that can only be dealt with on a worldwide basis, such as nuclear proliferation, the environment, the population explosion, and economic interdependence. For America, reconciling differing values and very different historical experiences among countries of comparable significance will be a novel experience and a major departure from either the isolation of the last century or the de facto hegemony of the Cold War, in ways which this book seeks to illuminate. Equally, the other major players are facing difficulties in adjusting to the emerging world order."
