Is Iran in the throes of revolution?

This editorial (and its checklist) suggests if it is not, it soon will be.

I also am pleased to see more media reports in the past 24 to 48 hours examining what happens once the daily protests fade. And they will, primarily because of the heavy-handed actions of the police. But the legitimacy of the Iranian regime has been significantly damaged, and its ability to do more than simply survive (i.e. North Korea) is a reasonable issue to discuss.

There also is the international reputation that Iran needs to consider, and the diplomatic efforts will be tedious. The religious clerics ought not be forgiven for what they have authorized, but at some point they will need to properly deal with the international community, unless it wants to become North Korea.
