The main points of this hard-hitting indictment of the Iraq war have been made before, but seldom with such compelling specificity. In dovetailing critiques of the civilian and military leadership, Washington Post Pentagon correspondent Ricks (Making the Corps) contends that, under Rumsfeld, Wolfowitz and Feith, the Pentagon concocted ""the worst war plan in American history,"" with insufficient troops and no thought for the invasion's aftermath. Thus, an under-manned, unprepared U.S. military stood by as chaos and insurgency took root, then responded with heavy-handed tactics that brutalized and alienated Iraqis. Based on extensive interviews with American soldiers and officers as well as first-hand reportage, Ricks's detailed, unsparing account of the occupation paints a woeful panorama of reckless firepower, mass arrests, humiliating home invasions, hostage-taking and abuse of detainees. It holds individual commanders to account, from top generals Tommy Franks and Ricardo Sanchez on down. The author's conviction that a proper hearts-and-minds counter-insurgency strategy might have salvaged the debacle is perhaps naive, and pays too little heed to the intractable ethnic conflicts underlying what is by now a full-blown civil war. Still, Ricks's solid reporting, deep knowledge of the American military and willingness to name names make this perhaps the most complete, incisive analysis yet of the Iraq quagmire. Photos.
