The Knight Ridder Washington Bureau has a story reporting that according to the Iraqi Ministry of Health, US and coalition action has killed or injured 66% of the Iraqis killed or injured in the insurgency. It quotes an American military spokesman as saying that “damage will happen.” The spokesman also says that “the insurgents were living in residential areas, sometimes in homes filled with munitions. ‘As long as they continue to do that, they are putting the residents at risk," he said. "We will go after them.’"
James Fallows has an interesting article in the October Atlantic (not available online) presenting all the things we could not or cannot do (the opportunity costs we have incurred) as a result of invading Iraq. The last paragraph reads in part:
The administration’s focus on Iraq “hampered the campaign in Afghanistan before fighting began and wound it down prematurely, along the way losing the chance to capture Osama bin laden. [Because of its focus on Iraq, the administration] turned a blind eye . . . to WMD threats from North Korea and Iran far more serious than any posed by Saddam Hussein . . . It overused and wore out its army in invading Iraq—without committing enough troops for a successful occupation. It saddled the United States with ongoing costs that dwarf its spending for domestic security. . . .”
