I'm still working the thought of the US, UK, & France staying more on the sidelines, Basically, maintain their unit locations at the end of OTL fighting.
IF the Republican Guard were shot up enough, and other Baathist controlled fighting resources are also reduced, to where Saddam would be overthrown, was there any scenario where Saudi Arabia, Qatar (with US material backing) move into Iraq as a peace keeping force? Or would that just add more ingredients to a toxic soup of religion and secular in-fighting?
