At the Pakistani military intelligence school, all officers must learn the difference between a coup and a revolution and history in depth in their curriculum. They are not the same regular forum people (whose guns are bigger !) or journalists you have seen in the last 15-20 years.
I have never seen any religious Iranian outside Iran in the last 40 years in Europe, America, and elsewhere. There are fake Iranian asylum seekers ( Afghani), of course.
I also have to correct you because Iran never had an Islamic revolution in 1979 in the real sense. Technically, it was a coup in which communists were also involved. Later, Khomenei killed his communist partners and hijacked the power on behalf of the mollahs. A coup never becomes a revolution by just claiming it. Real revolutions have some different characteristics.
@Aryobarzan can confirm it.
