I don't disagree, of course. All countries started out with dictators and juntas. (We called them kings in the Western world.) There should be a second movers advantage. Most of the clan cultures are gone at least, right?
Edit: Hmm... OK watwut -- the dictators have second movers advantage too? It seems to me that the reason evil juntas get fewer is that without an open society (which is hard without democracy) a country won't get above a certain economic level. The "Resource curse" counteract that and won't end in the Middle East until oil isn't critical.
