Hopes for a new peaceful international order after the end of the Cold War have been dashed by sobering realities: Great powers are once again competing for honor and influence. The world remains "unipolar," but international competition among the United States, Russia, China, Europe, Japan, India, and Iran raise new threats of regional conflict, and a new contest between western liberalism and the great eastern autacies of Russia and China has reinjected ideology into geopolitics.For the past few years, the liberal world has been internally divided and distracted by issues both profound and petty. Now, in The Return of History and the End of Dreams, Robert Kagan masterfully poses the most important questions facing the liberal dematic countries, challenging them to choose whether they want to shape history or let others shape it for them.
