Sorry but you really don't know what you're talking about here. Mossadeq was not "propped up by" anyone, he was elected twice by a fair vote in Majlis. The groups you refer to were especially vocal in supporting the oil nationalization program because they were anti-colonial, and were angry that Britain was in effect looting Iran's oil fields.Ummm...if you read the wikipedia article, I think you'll see that "overthrow a democracy and replace it with a dictator" is a the sort of simplification that abstracts a lot of salient point from the discussion, like, oh, say, the fact that Moussaddiq was propped up by the twin pillars of communists and radical islam
You are also oversimplifying the vote issue, the vote to dissolve parliament (a referendum not an election) was rigged by both sides, and one side was more successful than the other.rigged elections
Again you just don't know anything about this event, so stop lecturing on it. The Shah was acting as a puppet of Britain in preventing the nationalization of Iran's oil fields simply because Britain didn't want to lose its free oil. There is simply no case to be made that the Shah was a legitimate head of state acting under the rule of law. After the coup, Reza Shah became a dictator and gave the oil fields to an oil consortium with ownership split between US and British oil companies. He later created his own secret police/death squad, the SAVAK, with the help of the CIA, which murdered and tortured thousands of political prisoners.failed to leave office when dismissed, and was beaten down in his own coup attempt, in defiance of the existing legal system of the time.
We and Britain screwed Iran over royally, and the Islamic Revolution was the unfortunate side effect. After the revolution, we gave poison gas to Saddam Hussein which he used on Iranian civilians. I've driven around the abandoned US embassy a few times; the outer walls are still covered in anti-US murals. There are other murals around Tehran, but there seem to be fewer every time I go. Most Iranians are over it, especially considering that most Iranians were born after the revolution, but they (and we) are still suffering from a bad revolution that we made necessary.
