On March 24, Richard Clarke delivered a persuasive performance in front of the commission investigating the Sept. 11 attacks. Clarke—who has worked for Ronald Reagan, George H.W. Bush, Bill Clinton, and George W. Bush, serving as counterterrorism chief for the last two—apologized for his failures in fighting al-Qaida. Then he slammed the Bush administration for paying insufficient attention to the terrorist threat in the summer of 2001. His new book, Against All Enemies, makes similar points at greater length.
Although the book amounts to a chronicle of what many in the present Bush administration did wrong (and what Clarke and Clinton did right), it is neither shrill nor overly self-congratulatory. Unlike some of the books Slate has diced and julienned in this space, this one's worth reading, mostly for Clarke's informed account of al-Qaida's rise and the U.S. government's awareness of the threat. But since you may not have time to read the whole thing, Slate presents Clarke's most salient pieces of criticism and praise.
