It’s only a matter of time before the mullahs do a Tienanmen Square on the protesters. Once they kill 10 or 20 thousand of them like the Chinese did the people will fall back into place.
Some protesters have already been killed by government police squads. I read somewhere today that the military machine is mobilizing/gearing up to force the protesters to stand down.
If the mullahs do this, they still lose, as they will have proven that they're running an iron-fisted dictatorship, without question.
From that point forward, they will have zero legitimacy in the eyes of the people, and things will go downhill from there.
As if they weren't bad enough already.
