Ignore the dumb title because this book provides some very important context in a time of flag-waving empty-headedness. The author does draw many conclusions of his own, but mostly he simply corrals the best investigative reporting (much of it from major media sources), public testimony, and government documents into a coherent picture of why things went down as they did. The historical and political backstory provided is crucial to dispelling the apalling myth that we were attacked out of the blue and nothing could be done about it. The tone is incredulous and even-handed rather partisan or ideological. The facts presented in this book rocked me to my very core and left me mad as hell. (Compare the facts in this book to the 9-11 Commission Report and decide for yourself.)
