With Iraqis Saddamists and tribes? Maybe 50,000-75,000
Only problem is the assumption that "Iraq is a mess" which all these "Analysis" accept as the base for thier forcasting is a media created lie.
Read the data. Iraq is a winning mission that the Leftist are trying desperately to turn into a loss for domestic political reasons.

I just wish we'd give Musharif the ultimatum that if he's not going to send the Pakistani military into NW Pakistan on the border with Afghanistan and shut down the Taliban and Al Qaeda and Islamic Jihad and other Islamo-Fascist areas, then he needs to show us where his military IS in control, and give us tacit authorization to bomb the h**l out of those areas when we find enemy groups. That's what I wish. I'd also ask when Musharif is planning to have full and free open elections in Pakistan since he became "President" after the military coup, and he was never really elected. I'm so sick of these people like him, and Ahmadinejad and Hussein and Jong-Il and other tyrants taking the title of President when their countries do NOT have democracies in their countries, and they were NOT elected with the majority of votes of the people in full free elections. It's offensive to those countries that the majority of the civilian populous actually ELECTED their Presidents.
