Book excerpt: "A ... chronicle of the reasons behind Iraq's descent into guerrilla war, warlord rule, criminality, and anarchy ... It features candid interviews with high-ranking officials ... as well as Iraqi civilians, American soldiers, intelligence officers, and prominent analysts... Together, these voices reveal the principal errors of U.S. policy -- using insufficient troop levels, allowing the looting of Baghdad, purging professionals from the Iraq government, and disbanding the Iraqi military -- errors that largely created the insurgency and chaos that engulf Iraq today. The book brings the movie up-to-date by evaluating the military's recent 'surge' tactic as well as current administration policy. It concludes with a wide-ranging debate on the crucial question: what do we do now?"--P. [4] of cover.
