Sure, and that argument either leads to the obvious civil war that would happen after Saddam was taken out, or keep Saddam there.

Either way. There was no plan to handle any scenarios. Keeping our military there forever is not a plan as well, especially with no status of forces agreement under Bush or Obama.

ISIS was/is a natural event that has only been held in check with dictators in the ME.

ISIS grew largely because of a Dictator in Syria blowing his own people up.
