Just goes to highlight the folly of going in there in the first place...Saddam was a tyrant who murdered his own population, was a threat to western interests, harboured terrorism...
Man, I'm glad we fixed all that up.
Sending troops in now is as senseless as it was then. Like the cops with drug dealers, just let them knock each other off until there is one left standing, and then deal with him. Israel will have to step in eventually if the last man standing is one of the bad guys (e.g all of them) and decides to keep his troops on the march.
Until that happens it's better just to watch the place burn and pray for the innocents. The only way of stopping the bad guys melting back into to general population is to give them no reason to. Let them all keep fighting til they meet their virgins.
