Abstract

The nature of a global arena dominated by one great power remains a critical subject for understanding international relations. Brooks and Wohlforth's recent book makes an important contribution by arguing that unipolarity poses few constraints to the hegemon and that the United States today should pursue a policy of primacy. The puzzle is that the United States has mostly resisted a primacy policy since becoming the sole superpower, and when it has done so, has often been less successful than the promise of its power advantage. Explaining this puzzle requires building on ‘the no constraint’ approach to develop a positive theory based on hegemonic purpose, a reformulated notion of constraints, and how purpose and constraints interact to shape outcomes. This reformulation suggests that any American strategy that looks like ‘primacy’ is unlikely to succeed.
