Book excerpt: The past few years have witnessed changes which will be of lasting significance in international affairs. The revolutions in Eastern Europe and the Soviet Union, for example, are fundamental not only for those societies but also in their implications for the rest of the world. They signal the passing of the international order that has governed the post war era. Since the United States was the principal architect of that order, its passing will have fundamental implications for America's role in the modern world. It has been suggested that this transformation will reduce the US to the status of an ordinary country, indeed that the signs of decline are already everywhere apparent. In this book, the author argues to the contrary that the emerging new world order offers great opportunities to the US to maintain its status as the leading power in the world.
