When US Marines kill Iraqi civilians it is called "chaos of Iraq"

"One by one, the Marines sat down, swore to tell the truth and began to give secret interviews discussing one of the most horrific episodes of America’s time in Iraq: the 2005 massacre by Marines of Iraqi civilians in the town of Haditha.  “I mean, whether it’s a result of our action or other action, you know, discovering 20 bodies, throats slit, 20 bodies, you know, beheaded, 20 bodies here, 20 bodies there,” Col. Thomas Cariker, a commander in Anbar Province at the time, told investigators as he described the chaos of Iraq. At times, he said, deaths were caused by “grenade attacks on a checkpoint and, you know, collateral with civilians.”"
