The recent elections were never going to take power away from the Mullahs
Maybe not in practice, but that wish appears to be what's behind the demonstrations. No wonder the "authorities" both suppressed the true result of the election and were quite prepared to suppress the resulting demonstrations with whatever force/brutality was necessary. This junta has as much right to rule Iran as the Taliban did Afghanistan. The thing is, how will they be removed, because they sure as heck aren't going to give up gracefully.
