ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book discusses the range of options available to any state is constrained by the international distribution of power. It describes the changing balance of power also lead to a transformation of the distribution in relative responsibilities by each state for preserving the stability of the international system. The book argues that a new balance of power-the United States vis-a-vis Europe-will lead to a redistribution of responsibilities among actors such as maintaining international stability or European security, though states are too reluctant to adapt to the new realities. The faltering of the Soviet Union, the disintegration of the once monolithic Communist bloc, the end of the Cold War, and the reunification of Germany and Europe signify the most radical changes in the political map of Europe since the end of World War II.
