Put Mousavi, and you will have chaos. For one, the youth. Half of them, if not more, were just looking for an excuse to riot. This happens all the time. Nor does the youth have any understanding of real politics, or of what is possible in Iran, and what is not. Iran is a theocracy. You can slowly decrease the clerical influence, but this process is best executed slowly (unless for some reason you gain overwhelming popular support). My bet was that with Mousavi, little would change. If he tried to do any real reforms, that would be his end.
Too much instability. Iran is not ready for Mousavi. Try something centre-right - that by itself will be a miracle.
