My prediction - Iraq crumbles like yesterday's toast with no nukes used and feeble attempts by Saddam to deliver some gas and/or germs before he is found hanging from a lamppost with his girl friend. This guy is just another pissant dictator with some nasties, but cannot be left around to grow in stature if we backed down now.
Anybody ever notice the striking similarity of Saddam and Mussolini on their balconies, one shooting his rifle in a silly hat, and the other with his arms crossed and a silly smirk? The same fate awaits.
