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. Nation-states remain as strong as ever, as do the old, explosive forces of ambitious nationalism. The world remains “unipolar,” but international competition among the United States, Russia, China, Europe, Japan, India, and Iran raise new threats of regional conflict. Communism is dead, but a new contest between western liberalism and the great eastern autocracies of Russia and China has reinjected ideology into geopolitics. Finally, radical Islamists are waging a violent struggle against the modern secular cultures and powers that, in their view, have dominated, penetrated, and polluted their Islamic world.
