From the New York Times bestselling author of The Pentagon's New Map , a bold, trenchant analysis of the post-Bush world In Great Powers, New York Times bestselling author and prominent political consultant Thomas Barnett provides a tour-de-force analysis of the grand realignments in the post-Bush world-in the spheres of economics, diplomacy, defense, technology, security, the environment, and more. The "great powers" are no longer just the world's nation- states, but the most powerful and dynamic influences on the global stage, requiring not simply a course correction, but a complete recalibration. Globalization as it exists today was built by America- and now, Barnett says, it's time for America to shape and redefine what comes next.
