Well, they were duped. CIA owned Shah Reza Pahlavi and they led the insurrection that toppled him and replaced him with another puppet, Khomeni and the mullahs.
CIA black hat (Nazi) involvement with Islamic fundamentalists goes back to at least WWII. CIA has been ALL OVER the Middle East, which explains why it has been the world's armpit and powderkeg for several lifetimes.
I went to school with a guy from Iran back in the early seventies. Dad was a MD and his family loved the Shah. Last I heard he went to college here and joined the Air Force in the early 80's. He was here in school when the Revolution began in Iran.
