But keep in mind that overthrowing Saddam will be the easy part
US military occupation of Iraq and the work of crafting a viable, stable post-Saddam government will be the tough part. Many of the nations in the region are telling the US and UK that they're willing to look the other way and to keep their local anti-American lunatics under control during the war, but please do it quickly and please do not leave a mess in Iraq when it's over.
The war is necessary but there will be a lot of hard work to do afterwards.
