Kevin Sullivan thinks the term revolution is being thrown around too liberally:

It's also important to keep some perspective when comparing modern day Iran to the Iran of 1978 and 1979. While this week's demonstrations in Tehran have been impressive, they've yet to reach the range and level of participation as the national strikes and demonstrations of the Khomeinist revolution. As far as we can tell, the current upheaval is mostly isolated to Tehran. And while the many thousands marching on behalf of Mir Hossein Mousavi's election challenge are indeed awe-inspiring, they do not come close to the numbers reached during the Iranian Revolution, when anywhere between 25-30 cities per day were consumed by riots and upheaval. It's believed that nearly 10% of the Iranian population participated in those demonstrations at their height, which is simply unheard of in the history of popular protest.
