Query: This book is amazing!

I've followed many of the Bush Administration exposes that have appeared in the first half of 2004 -- from Paul O'Neill to Bob Woodward to John Dean. Richard Clarke's is the juiciest. Clarke is the consummate insider: he has long-standing credibility among Republicans and Democrats alike, and his message is clear. The Bush Administration has been afflicted with an obsession with Iraq that has led the United States horribly astray in the fight against terror. Ironically, some of the revelations of June and July 2004 have made Clarke's criticisms from only a few months before seem mild in comparison.A caveat -- Clarke isn't a terrific writer, and he's got an overinflated sense of self-importance. But does this detract from the book's relevance and impact? Not a bit.
