Very valid points. But how would you be able to tell whether the majority of Iranians aren't happy with their Government with confidence?

I find that difficult to believe because, if that were the case, at some point, specially because of all the reasons you mentioned, the people would just get over it and kick the current Government out of office for good?! It may be bloody, but if the people really want it, it's not unreasonable to assume, IMHO, that the military would be onboard with it?? Once the military is on board, there's nothing the politicians and cleric can do to stop it as in a revolution, the only thing that matters is physical power.
