Here is the New York Times and international best seller, revised and expanded with a new afterword. This is the essential update of Fareed Zakaria's analysis about America and its shifting position in world affairs.

The Post-American World pointed to the rise of the rest - the growth of countries China, India, Brazil, and others - as the great story of our time, the story that will undoubtedly shape the future of global power. Since its publication, the trends Zakaria identified have proceeded faster than anyone could have anticipated. The 2008 financial crisis turned the world upside down, stalling the United States and other advanced economies. Meanwhile, emerging markets have surged ahead, coupling their economic growth with pride, nationalism, and a determination to shape their own future.

In this new edition, Zakaria makes sense of this rapidly changing landscape. With his customary lucidity, insight, and imagination, he draws on lessons from the two great power shifts of the past 500 years - the rise of the Western world and the rise of the United States - to tell us what we can expect from the third shift, the rise of the rest.

The great challenge for Britain was economic decline. The challenge for America now is political decline, for as others have grown in importance, the central role of the United States, especially in the ascendant emerging markets, has already begun to shrink. As Zakaria eloquently argues, Washington needs to begin a serious transformation of its global strategy, moving from its traditional role of dominating hegemon to that of a more pragmatic, honest broker. It must seek to share power, create coalitions, build legitimacy, and define the global agenda - all formidable tasks.

None of this will be easy for the greatest power the world has ever known - the only power that for so long has really mattered. America stands at a crossroads. In a new global era in which the United States no longer dominates the worldwide economy, orchestrates geopolitics, or overwhelms cultures, can the nation continue to thrive?
