Btw one addition - we all know that US embassy was stormed and employees held hostage in 1979. It gave US political ammunition for decades to come. Do you know why it was stormed? Because it was proper CIA headquarters in all this meddling and impoverishment of iranian people for decades. They shielded themselves with diplomatic immunity. Not something you see mentioned in the (rather bad for all that empty patriotism) movies. But wouldn't you be pissed off if they did this to your own country? To have the potential for greatness due to rich oil reserves, but having little from it because some foreign power installs corrupt ruler to have safe access to oil. Sounds like an african story.
Those employees taken? Most were involved or directly in CIA payroll. No respect there, nor much sympathy. Spies are generally either executed or traded for.
