The Age of Nonpolarity

What Will Follow U.S. Dominance

Richard N. Haass

From Foreign Affairs, May/June 2008

Summary:  The United States' unipolar moment is over. International relations in the twenty-first century will be defined by nonpolarity. Power will be diffuse rather than concentrated, and the influence of nation-states will decline as that of nonstate actors increases. But this is not all bad news for the United States; Washington can still manage the transition and make the world a safer place.

RICHARD N. HAASS is President of the Council on Foreign Relations.

The principal characteristic of twenty-first-century international relations is turning out to be nonpolarity: a world dominated not by one or two or even several states but rather by dozens of actors possessing and exercising various kinds of power. This represents a tectonic shift from the past.

The twentieth century started out distinctly multipolar. But after almost 50 years, two world wars, and many smaller conflicts, a bipolar system emerged. Then, with the end of the Cold War and the demise of the Soviet Union, bipolarity gave way to unipolarity -- an international system dominated by one power, in this case the United States. But today power is diffuse, and the onset of nonpolarity raises a number of important questions. How does nonpolarity differ from other forms of international order? How and why did it materialize? What are its likely consequences? And how should the United States respond?

NEWER WORLD ORDER

In contrast to multipolarity -- which involves several distinct poles or concentrations of power -- a nonpolar international system is characterized by numerous centers with meaningful power.

In a multipolar system, no power dominates, or the system will become unipolar. Nor do concentrations of power revolve around two positions, or the system will become bipolar. Multipolar systems can be cooperative, even assuming the form of a concert of powers, in which a few major powers work together on setting the rules of the game and disciplining those who violate them. They can also be more competitive, revolving around a balance of power, or conflictual, when the balance breaks down.

At first glance, the world today may appear to be multipolar. The major powers -- China, the European Union (EU), India, Japan, Russia, and the United States -- contain just over half the world's people and account for 75 percent of global GDP and 80 percent of global defense spending. Appearances, however, can be deceiving. Today's world differs in a fundamental way from one of classic multipolarity: there are many more power centers, and quite a few of these poles are not nation-states. Indeed, one of the cardinal features of the contemporary international system is that nation-states have lost their monopoly on power and in some domains their preeminence as well. States are being challenged from above, by regional and global organizations; from below, by militias; and from the side, by a variety of nongovernmental organizations (NGOs) and corporations. Power is now found in many hands and in many places.

In addition to the six major world powers, there are numerous regional powers: Brazil and, arguably, Argentina, Chile, Mexico, and Venezuela in Latin America; Nigeria and South Africa in Africa; Egypt, Iran, Israel, and Saudi Arabia in the Middle East; Pakistan in South Asia; Australia, Indonesia, and South Korea in East Asia and Oceania. A good many organizations would be on the list of power centers, including those that are global (the International Monetary Fund, the United Nations, the World Bank), those that are regional (the African Union, the Arab League, the Association of Southeast Asian Nations, the EU, the Organization of American States, the South Asian Association for Regional Cooperation), and those that are functional (the International Energy Agency, OPEC, the Shanghai Cooperation Organization, the World Health Organization). So, too, would states within nation-states, such as California and India's Uttar Pradesh, and cities, such as New York, São Paulo, and Shanghai. Then there are the large global companies, including those that dominate the worlds of energy, finance, and manufacturing. Other entities deserving inclusion would be global media outlets (al Jazeera, the BBC, CNN), militias (Hamas, Hezbollah, the Mahdi Army, the Taliban), political parties, religious institutions and movements, terrorist organizations (al Qaeda), drug cartels, and NGOs of a more benign sort (the Bill and Melinda Gates Foundation, Doctors Without Borders, Greenpeace). Today's world is increasingly one of distributed, rather than concentrated, power.
