Consider a thought experiment. Let's go back to late 2002 and early 2003. Assume that the build up on the WMD front is more or less as it transpired. But assume, for our counterfactual, that the costs of what we were getting into had been made pretty candidly clear. Half a million troops to secure the place, maybe years of occupation and nation-building. Then you get to early 2003 when it was clear that even if there was some mustard gas hidden away somewhere, that beside those lamo rockets the inspectors found, there really weren't any big WMD programs or stockpiles. Remember, that was clear, before the war started. Once that was clear, and if people knew the costs of what we were getting ourselves into, is there any way the president would have had any support for still going to war, pretty much just for the hell of it? This is the key. Yes, the American people probably won't support what it takes to make this happen. That's because they make a perfectly rational calculation that so much blood and money for no particular reason just isn't worth it. They're only in this situation because President Bush and his advisors gamed the public into this war on false pretenses knowing that once they were it would be almost impossible to get back out. - - - Josh Marshall
