You are right to point this out and criticise Western foreign policy, but we have to avoid slipping into pro-revolutionary propaganda here. The American/British backed coup was a self-serving Cold War move with no concerns for the Iranians, but we must avoid framing the revolution in a way that risks romanticising the action as a form of liberation when, in reality, it was the replacement of one form of repression for another. The Shah was still Iranian, which matters here. Whether intended or not, statements like these end up seeming to justify the theocratic authoritarian regime that rules Iran today, which absolutely should not be the case.
