The false promise of unipolarity: constraints on the exercise of American power

In World out of balance, Stephen Brooks and William Wohlforth make a valuable contribution to ongoing debate about the systemic effects of unipolarity and the durability of US primacy. They are correct that unipolarity engenders systemic stability because the power gap between the United States and potential rivals forestalls military balancing. However, Brooks and Wohlforth underweight other means through which major states are resisting US power and they fail to appreciate that the systemic characteristics of unipolarity may change in relatively short order.
