How do you think that would play out?
I don't think Iran has the military capability to project any power this way. It doesn't matter what people here ask for. The best they can hope for is being armed from across the moat in order to fight their own battles. That can only take the form of small arms and explosives (and a protracted guerrilla-style campaign is not good for expats).
Rumour has it that the protesters have been given til Sunday to exit the pearl. We will see what transpires.
