I disagree. Saddam would have likely just installed a puppet dictator who he could control or have a planned successor. Essentially Saddam would have put in place procedures to ensure that the Shiites and Kurds stayed repressed. However, if we mandated a democracy, it is likely that civil war would have broken out.
In many ways the civil war is over. The passage of time has fixed what the mess the Europeans left. The Shiites now live primarily in Shiite areas, the Sunnis in their own, the Kurds in their own. The Europeans SHOULD have made countries based on homogeneous groups, but what is done is done and we have seen in the past 5 years groups taking it upon themselves to homogenize their enviroments, often through violence. Now the Shiites are just largely fighting for power between themselves.
