The unipolar moment has passed. Even old allies stubbornly resist American demands, while many other nations view U.S. policy and ideals as openly hostile to their own. Washington is blind to the fact that it no longer enjoys the dominance it had at the end of the Cold War. It must relearn the game of international politics as a major power, not a superpower, and make compromises. U.S. policymaking should reflect rational calculations of power rather than a wish list of arrogant, unilateralist demands.

THE NEW DIMENSION OF POWER
During the past decade global politics has changed fundamentally in two ways. First, it has been substantially reconfigured along cultural and civilizational lines, as I have highlighted in the pages of this journal and documented at length in The Clash of Civilizations and the Remaking of World Order. Second, as argued in that book, global politics is also always about power and the struggle for power, and today international relations is changing along that crucial dimension. The global structure of power in the Cold War was basically bipolar; the emerging structure is very different.
There is now only one superpower. But that does not mean that the world is unipolar. A unipolar system would have one superpower, no significant major powers, and many minor powers. As a result, the superpower could effectively resolve important international issues alone, and no combination of other states would have the power to prevent it from doing so. For several centuries the classical world under Rome, and at times East Asia under China, approximated this model. A bipolar system like the Cold War has two superpowers, and the relations between them are central to international politics. Each superpower dominates a coalition of allied states and competes with the other superpower for influence among nonaligned countries. A multipolar system has several major powers of comparable strength that cooperate and compete with each other in shifting patterns. A coalition of major states is necessary to resolve important international issues. European politics approximated this model for several centuries.

NATO's poorly planned adventure in Kosovo has brought a critical question to the fore: just how should Americans define their national interest in the information age? The Soviet Union is gone, and an information revolution has transformed the nature of power. Few "A list" threats to American security loom large today. Global telecommunications have made humanitarian crises in far-flung places impossible to ignore. But before the United States embarks on another costly human rights crusade, Americans should recognize that moral values are only part of a foreign policy. Other essential priorities remain. If Washington neglects to handle the "A list," the consequences for global peace and prosperity will be dire.
Secretary Cohen's defense review is out, but the flaws in the Pentagon's military planning are still glaring. Haiti, Bosnia, NATO expansion, stability in Korea, keeping Iraq in check-all these are primarily army and air force missions. Yet the army has been reduced by about 40 percent, while the navy has been cut back far less and the marines hardly at all. Advances in technology make the marines' expeditionary role and the navy's aircraft carriers obsolete. Defense doesn't need more money; it needs to reallocate resources. As it stands, the United States is paying more for a military that can do less.
When Congress swings the budget ax, it cripples U.S. foreign policy. Now is the time to make a virtue of necessity and craft a system both leaner and better able to promote America's aims abroad.
