That the Islamists never liked Mossadeq (to put it mildly) is part of Taheri's story as well. Let me quote the pertinent paragraph:
Clinton’s claim that the United States changed the course of Iranian history on a whim would be seen by most Iranians, a proud people, as an insult by an arrogant politician who exaggerates the powers of his nation more than half a century ago. Moreover, in the Islamic Republic that Clinton was trying to court, Mossadeq, far from being regarded as national hero, is an object of intense vilification. One of the first acts of the mullahs after seizing power ni 1979 was to take the name of Mossadeq off a street in Teheran. They then sealed off the village where Mossadeq is buried to prevent his supporters from gathering at his tomb. History textbooks written by the mullahs present Mossadeq as ”the son af a feudal family of exploiters who worked for the cursed shah, and betrayed Islam.” Clinton’s apology to the mullahs for a wrong supposedly done to Mossadeq was like begging Josef Stalin’s pardon for a discourtesy towards Alexander Kerensky.
However, in a more general perspective this story shows how pernicious the Cold War propaganda was, and the fact that the West very seldom was able to properly refute the lies and misinformation coming from the Soviets and their fellow travelers. The latter have now, completely unashamed, changed horses and instead of materialist Marxism they are now supporting "Third Worldism" and Islamism.
It was the college freshman who said, ““Iran’s Islamist dictators were “a predictable consequence of American imperialism,” which prompted the article and that’s what prompted my original & subsequent response.
Another good source to read to cross check some facts about Mossadegh, Islamists and Communists in Iran, is the memoirs of the late Shah’s wife, Empress Farah.
In her book, she writes that whilst there was an active effort to rein in the communists in Iran & SAVAK actually had a mandate to arrest communists, the mullahs & islamists in Iran were LARGELY left untouched to give anti-monarchy sermons in mosques and other gatherings, particularly in smaller towns and among lower-class groups in Iran.
