US and Iran

I have been reading a history of US and Persian/Iranian relations. Seeing how the people in Iran went from seeing the US as role models then to protectors to oppressors is staggering. It didn't take long for the US to dive into coups and countercoups to establish a pro US government. And to back the Shah, no matter what campaign promises about human rights were spouted up til 1979. My experience previous to this has been my own memories of the US hostages from 79-80. I remember the yellow ribbons and the 444 days. I just remember wondering how can these people hate us so much? Now I think I have a better idea. Its more than just Islamic Fundamentalism, though that plays a big part. It is about how people were treated and basically exploited for decades. That is bound to build up resentment.
