Decided to Google a little history. Checked out the overthrow of Prime Minister Mosaddeq by the US CIA and British MI6 in 1953, at the beginning of the Eisenhower Admin with Allen Dulles (CIA) and John Foster Dulles, (State). Apparently the British who had controlled IRanian oil since 1913 were not willing to do a 50/50 share deal as Aramco had agreed to with the Saudis.
Mosaddeq was elected PM in parliament by 79 to 12. Apparently the Shah was afraid of his popularity, and the clerics did not like that he was a secularist. So what would have happened if we had not interfered with what was then a lot more of a Free and Secular Persia? See detailed story:

Wikipedia is written up by Mossadegh supporters not his opponents so perhaps you should read the following articles found on AntiMullah to get the full and ACCURATE picture:
In the search box on http://antimullah.com I typed in “Mossadegh” and got a bunch of articles. Here are the most pertinent AND informative ones. GOOD READS if you want to learn the real facts.
