The book discusses the dangers of the "unipolar view" of world politics, one in which the United States is overwhelmingly predominant and should act accordingly. The book notes the damage caused by this view in action - as in the Middle East and Europe. It assesses the real strengths and weaknesses of American power - "soft," military, economic, and moral. It contrasts the federal systems of "Old America" and "New Europe" as models for governing today's increasingly plural system. It notes how friendly balancing from Europe is critical for maintaining America's own constitutional equilibrium.
