The fundamentalists were already extremely powerful before the coup. In fact, they formed a huge base of support for Mossadegh(strange bedfellows, since he was largely secular, but whatever gets you in power right?). And before the coup, they had already broken with him. If Mossadegh remained in power, why do you think the fundamentalists would not have just performed the coup themselves, leading Iran to a fundamentalist regime just a few years earlier than they did against the Shah? I find these analyses strange, as if Iranian people lack autonomy, and are merely passive victims to the vicissitudes of Western will.
