Why are liberals so upset about our success in Iraq?

Our military has easily kept Al Qaeda bogged down in a quagmire in Iraq.............they are way to busy to even contemplate a serious atttack on the usa.................Osama wants out of Iraq because the cost of the war is breaking him and his backers..........................and the more muslims he kills everyday , the more they hate him..............Why does the failure of Al qaeda causing liberals to hate bush?
