The key, the thing to watch, is the relationship between the ruling Imams and the military leadership. If the rulers feel the populace is getting too restless they will go to war against ‘someone’. [See Ez38]
The next revolution has to be bloody with the Imans and their supporters hung.
When they (this includes Westernized young people) stop chanting Death to America and Death to Israel...maybe God will relent and give them freedom.
