As always you never get anything right! The Brits and the Americans were very worried that the Soviet Union would just move in and take everything lock stock and barrel. You are like so many lefties, you can only use Presentism to interpret historical events. Mohammad Mosaddegh was many things but he was not a great democrat, not sure anybody could be in the post war turmoil in the Middle East.
Why don't you apportion blame to the French who gave Khomeini a safe haven in Paris for all those years, never heard a lefty yet that even mentions that fact!
Mossadeq was a far better leader for the people than the Shah who got fabulously rich giving oil companies what they wanted. I live in an area that is over 30 percent Arab. They still point to our overthrow as the beginning of the Arab disaster. https://foreignpolicy.com/2019/10/30/the-united-states-overthrew-irans-last-democratic-leader/ Rightys cannot type without insults. try and do better.
