and on the "insurgents" from 2003 to 2006---some 40,000 killed, about 200,000 wounded, 20,000 captured, and nearly 10,000 deserted. He has stated that those levels of attrition on an enemy the estimated size of al-Qaeda were substantial and deeply damaging, not only to the terrorists' efforts in Iraq, but had the effect of depleting them worldwide. Moreover, Schweikart argued, virtually all estimates of enemy casualties were severely under-counted (as are all numbers of guerilla casualties) given the inability to identify bodies which were completely annihilated by explosives or to count carcasses dragged away, as well as how many would die later after attempted medical treatment by other Al Queda sympathizers. On September 11, 2014, Senator John McCain argued on CNN's At This Hour that the surge was a victory, that it had fulfilled the goal of providing substantial security and stability to the Iraqi government, and that the withdrawal of troops after the surge had resulted in growing terrorist operations and the emergence of ISIS in Iraq. McCain said, "We had it won, thanks to the surge. It was won. The victory was there. All we needed was a force behind to provide support, not to engage in combat, but to supply support, logistics, intelligence. And, by the way, the Korean War we left troops behind; Bosnia, we left troops behind, not to fight, but be for a stabilizing force."

He has stated that "the battle for Baghdad in 2006-07 was won by the Shia, who now control three-quarters of the capital. These demographic changes appear permanent; Sunnis who try to get their houses back face assassination." UCLA professor of geography John Agnew released a study in mid-September 2008 stating that violence has declined in Baghdad "because of intercommunal violence that reached a climax as the surge was beginning," said that "By the launch of the surge, many of the targets of conflict had either been killed or fled the country, and they turned off the lights when they left." Washington Post reporter Bob Woodward has interviewed US government sources according to whom the US "surge" was not the primary reason for the drop in violence in 2007–2008. Instead, according to his view, the reduction of violence was due to new covert
