Fukuyama, Francis. America at the crossroads. Democracy, power and the neoconservative legacy. New Haven: Yale University Press, 2006.

"I have concluded that neoconservatism, as both a political symbol and a body of thought, has evolved into something that I can no longer support. As I will try to demonstrate, neoconservatism was based on a set of coherent principles that during the Cold War yielded by and large sensible policies both at home abroad. The principles, however, could be interpreted in a variety of ways, and during the 1990s they were used to justify an American foreign policy that overemphasized the use of force and led logically to the Iraq war. Neoconservatism has now become irreversibly identified with the policies of the administration of George W. bush in its first term, and any effort to reclaim the label at this point is likely to be futile. It is much more important to redefine American foreign policy in a way that moves beyond the Bush administration’s legacy and that of its neoconservative supporters."
