"Halper and Clarke have crafted an engrossing tale about the roots and impact of neo-conservatives on American policy. The book is must reading not only for what it says about how they did it, but also for documenting the paucity – in the U.S. government and beyond – of meaningful debate about the potential risks as well as benefits of mounting 'preventive' war in response to the events of September 11, 2001."
- Chester A. Crocker, Former Assistant Secretary of State for African Affairs, and James R. Schlesinger Professor of Strategic Studies, Georgetown University
