So, having illegally invaded Iraq and provoked a civil war, at the cost of an estimated 655,000 lives, the US is now saying that it's Iraq's responsibility to clean up the mess, and threatening "consequences" if they don't. Talk about blaming the victim!
At this stage, its difficult to see what they can do. The war is unwinnable, the stated aim of a free and democratic Iraq to serve as an inspiration to the region unachievable (by American methods at least). Staying around means they provoke more violence (but paradoxically, increases the chances of a united Iraq). Withdrawing means watching a bloodbath (but on the plus side, at least they won't be making things any worse, and there won't be any more blood directly on their hands; on the minus, it will still be their fault for having caused it in the first place). So instead they're now openly talking of installing a "strongman" to "stabilise" the country - a betrayal of the very reasons they supposedly invaded in the first place. But I suppose to American eyes, that's better than admitting you were wrong and that you should never have invaded in the first place.
