In this chapter, I first show that, notwithstanding its catchy and provocative title, The Post-American World actually makes a case for continued US geopolitical preeminence, not one for the transformation of the unipolar order. Second, I demonstrate that, contrary to Zakaria’s argument, unipolarity is rapidly coming to an end because of the rise of new great powers, the relative decline of US economic power, and US “imperial overstretch.” Third, I argue that the real post-American world is likely to be one of intense great power competition and that the institutional foundations of the Pax Americana will give way to a new international order in which US influence is sharply diminished.
