I suspect that you are mistaken, Teribus, about none of it being at the instigation of the US. I am sure the USA does everything it can to covertly assist any and all Iranian protest groups....just as Iran does everything it can to assist the Shia groups that attack people in Iraq or elsewhere.

Really, be realistic. They ALL channel money, arms, and other support to whomever will attack their "enemy"...on the old principle: "the enemy of my enemy is my friend"

I agree that ending the reign of the 12 Old Gits in Iran would be an excellent idea, and would benefit Iran in the long run...(but I don't favor starting another full-scale war with Iran to accomplish that).
