With Iran anyway, back in the 60's we took out the old religious leaders and put in the Shar. He was way to aristocratical for the average Iranian and to this day they still haven't forgiven us from inserting the Shar. We are known as a force that wants to colonize the world in the eyes of the Iranians. It snowballs from their with our protection and arming of Israel, now the US is the head of the great Satin That's how I read into it.
Actually Buff, it was 1953, and Mossadegh was an extremely popular, & democratically elected secularist. His mistake was wanting to ensure that the lion's share of Iranian wealth, went to the Iranian people and not to British oil firms.
The disdain for the Shah was not found in his 'aristocracy', but rather in his brutality, greed & corruption. He was a vile & brutal dictator who made good use of his CIA trained & developed Savak secret police. It was that overwhelming rejection of western corruption & oppression, that threw so many into the arms of the Islamic fundamentalists.
The rise of Islamic fundamentalism throughout the world is a direct consequence of US interventionism, ...both then, and NOW.
