The article does not focus on the handful of atrocities that have gotten substantial press coverage, like the massacre in Haditha in November 2005. Instead, based on interviews conducted on the record with dozens of American combat veterans of the war, the authors address what they describe as frequent acts of violence in which U.S. forces have abused or killed Iraqi civilians - men, women and children - with impunity.

The combination of recklessness, wantonly destructive behavior born of panic and deliberate acts of cold-blooded violence by G.I.'s are believed to have cost the lives of thousands of innocent Iraqis, the article says. The soldiers interviewed said they believed that only a minority of U.S. troops engaged in objectionable behavior, but the toll of their actions has been huge.

The article describes soldiers and marines frustrated and fearful in an alien environment in which the enemy hides among civilians and uses acts of terror as the primary tactic. "The mounting frustration of fighting an elusive enemy and the devastating effects of roadside bombs, with their steady toll of American dead and wounded, led many troops to declare an open war on all Iraqis," said the authors, Chris Hedges, a former Middle East bureau chief for the New York Times, and Laila al-Arian.
