Also, out of curiosity--do you think that Iraq would have experienced a Sunni Arab rebellion had the U.S. helped the Shiites and Kurds overthrow Saddam Hussein back in 1991? Or were sectarian tensions in Iraq back then not yet that deep--thus preventing a Sunni Arab rebellion from breaking out in Iraq afterwards?
If the US tossed in for another few days a lot of secular Iraqi soldiers would have backed the revolution.
As it stood most of the army didn't fight to put down the Revolution, the Republican Guard did that.
