. . .
Mistakes have been made within and without (apart from the mistake of 1979) and many in the commentaries here as well.
My concerns is only the violence and how to tell the students and public to stop. Why? Because what was needed (to tell the regime that things have got to change) was done. There is no doubt that government wants to stay in power and are willing to fight for it, so either a full blown revolution will take place (with a probable loss and an even more hard-line government) OR they go home now with some pride and note that the more moderate (but "within the system") politicians (Ali Akbar Hashemi Rafsanjani and Co.) will certainly make capital and destabilize from the top down. At worst, let the population suffer another four years and the likelihood is that change will happen.
