I have talked to Iranians who left Iran when the shah was disposed and they HATE the islamists with a passion.
They state that they are Iranian people, Zoroastrians, NOT muslims.
I don’t think it would take much to push the Iranian people over the edge.
I’ve met a dozen “Iranians” in the US including 2 co-workers. They all called themselves Persian.
I knew a bunch of Iranians, who were going to pilot training in Del Rio, by golly Texas. The USAF pulled them out of pilot training in 1979. The ones I talked to, were not happy going back, but it was at Laughlin, that I figured out, that the Iranian Air Force would be no match for US and Israeli pilots. Those guys could not fly airplanes, to save their lives.
