There are a number of stable prosperous multiethnic states. In the specific examples of Iraq, Syria, and Libya though, part of the specific rationale for the U.S. moving in to overthrow the dictator was that the dictator and his ethnic group were oppressing the rest of the country. If democracy is instituted, and the ruling group was a minority, there will be resentment on the side of the majority for past treatment, and resentment on the side of the formerly ruling minority for their diminished status. This has a tendency to boil over into civil war. This is exactly what happened in Yugoslavia, and we solved it by breaking up the country, and it has been fairly peaceful for twenty years. The main place where there are still problems is in Bosnia, and specifically because we left Bosnia together and the Bosnian Serbs want out.
