Approximately 83 percent of Americans surveyed said recent incidents such as a car bomb explosion that killed 40 in the city of Kut, the executions of seven worshippers outside a mosque in Youssifiyah, and a series of other attacks that have left scores of Iraqis dead and wounded were the kinds of events that, if they didn't know better, might make them think the lengthy occupation really wasn't worth it in the slightest.
Forty-three percent of Americans said if someone wanted to, they could very nearly make the assessment, based on current conditions on the ground, that perhaps the United States wasted valuable resources on an unwinnable, nearly impossible endeavor.

A majority of Americans also agreed that the spate of roadside bombs, suicide attacks, and ethnic murders might—and this is just an opinion, they claimed, which may or may not actually hold water—cause one to deduce that the federal government had sacrificed 4,500 troops, not to mention more than 100,000 Iraqi civilians, in a campaign that ultimately, perhaps, proved ruinous for both nations.
