If you were Bush 2, what would you do to try to save your presidency? Attack Iran to hide Iraq's failure?

This possiblity was discussed on the Chris Matthews Show on NBC. With the generals and others who did not support the "surge" in Iraq now fired and replaced, who is left to restrain Bush 2 from a new war in Iran? Can Congress do it? Do we really believe they can? If he starts a war with Iran, will Congress be forced to start the drafting of America's young men (and probably women) for military service? Will you serve if ordered to report for duty on the new Iranian front? Have the recent changes in U.S. pport requirements been related to a future governmental need to deter Americans from leaving their own country, as many did during the Vietnam War?
