Iran then, Libya now?

The graphic novel we have been reading Persepolis has gone into some gruesome detail regarding the overthrow of the Iranian Shah and the forming of the corrupted government afterwards. This got me thinking about the future of the countries in Africa that are going through the same thing now. Will Lybia, once liberated, fall into the same problems that were faced by the people, or will support of other nations guide them in a better direction, a guidance that Iran did not have at the time. Will Egypt and Tunisia be better off because their previous leader gave up his power easily? I gues only the future will tell but we can hope that these nations will have peaceful transitions into these new governments and that the people in these nations can be happy.
