Wright, who state that “in empires, inter-societal divide-and-rule practices replace interstate balance-of-power dynamics.”[3]

Unipolarity is anarchical. Anarchy results from the incomplete power preponderance of the unipole. Columbia University's Kenneth Waltz, whom Monteiro cites, argues that a great power cannot “exert a positive control everywhere in the world.”[4] Therefore, relatively weaker countries have the freedom to pursue policy preferences independent of the unipole. The power projection limitations of the unipole is a distinguishing characteristic between unipolar and hegemonic systems.

Unipolar systems possess only one great power and face no competition. If a competitor emerges, the international system is no longer unipolar. Kenneth Waltz maintains that the United States is the only “pole” to possess global interests.[4]

The post-Cold War international system is unipolar: The United States’ defense spending is “close to half of global military expenditures; a blue-water navy superior to all others combined; a chance at a splendid nuclear first strike over its erstwhile foe, Russia; a defense research and development budget that is 80 percent of the total defense expenditures of its most obvious future competitor, China; and unmatched global power-projection capabilities.”[1]

William Wohlforth, the Daniel Webster professor of government at Dartmouth College, believes unipolarity is peaceful because it “favors the absence of war among great powers and comparatively low levels of competition for prestige or security for two reasons: the leading state’s power advantage removes the problem of hegemonic rivalry from world politics, and it reduces the salience and stakes of balance of power politics among the major states."[5] This idea is based on hegemonic stability theory and balance of power theory. Hegemonic stability theory stipulates that “powerful states foster international orders that are stable until differential growth in power produces a dissatisfied state with the capability to challenge the dominant state for leadership. The clearer and larger the concentration of power in the leading state, the more peaceful the international order associated with it will be."[5] Balance of power theory stipulates that as long as the international system remains unipolar, balance of power theory creates peace. “Therefore one pole is best, and security competition among the great powers should be minimal.”[5] Unipolarity generates few incentives for security and prestige competition among great powers.
