Probably the most important thing to deal with is regime change when the power vacuum is created with the departure of the mullahs. Who will fill it? Who will orchestrate the filling. Israel is not positioned for this job and we should only do it if we don’t require troops. It is a nation of 90 million and we sure don’t want it either. Russia probably does not want it, they have their own problem and future problem in Ukraine, China may want it but probably only wants the oil. We don’t care if they buy the oil and in fact that would be best for the replacement regime.
Iran is a highly educated nation of 90 million people. They will figure out who will be the next successor to the ruling Mullahs, if it gets to that point.
