The war in Iraq cost money (800 billion and counting), American lives (4500), and more than 100,000 Iraqi causalities (most of them civilians). It cost US the moral high ground after 9/11 and the International political leadership. By looking at the composition of coalition army, it was not that hard to see the unity behind US was gone by that point - even Canada did not send ground troops. A piss off to Bush of course. A war without a post war strategy, a war based on false intelligence, a war decried by most Americans towards the end, a war cost thousands of American lives and hundreds of thousands innocent civilian lives, can hardly be justified.. If the goal was for the oil, as many people pointed it out, the verdict of history on his Presidency can hardly be a good one.
