If come September, things are not better in Iraq, and IF the Republicans do join with the Democrats or even if they don't join with the Democrats on redeploying out of Iraq, what is Plan B?

What is the secondary, and new approach, to Iraq, if this one fails?

Over 100,000 Iraqis are being displaced a month due to the sectarian violence.

This means that they are already being divided in to tribal regions.

Do you think that we should be having discussins on whether to divi up Iraq in to 3 regions, and anticipate the possitives and negatives of doing such, if this is what the Iraqis want to do, or are ultimately doing with this civil war of sorts?
