The cutthroat world of international politics has always been dominated by great powers. Yet no great power in the modern era has ever managed to achieve the kind of invulnerability that comes from being supreme in its own neighborhood. No great power, that is, except one--the United States.

In We May Dominate the World, Sean A. Mirski tells the riveting story of how the United States became a regional hegemon in the century following the Civil War. By turns reluctant and ruthless, Americans squeezed their European rivals out of the hemisphere while landing forces on their neighbors' soil with dizzying frequency. Mirski reveals the surprising reasons behind this muscular foreign policy in a narrative full of twists, colorful characters, and original accounts of the palace coups and bloody interventions that turned the fledgling republic into a global superpower.

Today, as China makes its own run at regional hegemony and nations like Russia and Iran grow more menacing, Mirski's fresh look at the rise of the American colossus offers indispensable lessons for how to meet the challenges of our own century.
