No, nobody is ever forgetting that. It gets shoved into everyone's faces at EVERY opportunity. This is strange, because when it comes to moral failings, oil profits and corruption aren't on any serious person's radar.
Because what does get forgotten is that socialists worldwide strongly supported the revolution, from Moscow to Brazil, Berlin to New York, including supporting khomeini. With the UK's campaign "khomeini doesn't seek power, just wants to free Iran" message (spread by the BBC), and France's asylum and help. Protest marches in support of what turned out to be murderous islamists in every capital.
As for tactics: Khomeini (let's be honest here: it was Khomeini) organized snipers to shoot into the security services during a protest, provoking a battle where 89 people died ... at which point Khomeini declared that "4,000 innocent protesters were massacred by Zionists".
The protestors, whipped up by leftists did not take khomeini at his word, organized a general country-wide strike ... Khomeini organized further attacks on both his allies and the government, each time blaming zionists, never losing socialist support ... and 2 years later, now in power, Khomeini organized a massacre to "purify" Iranian society of his socialist allies, at least 3800 brutally executed, including high school students, one at most 7 years old. He has kept killing, and khamenei has continued the killings, some years 300, in the last decade more like 1000 every year.
Famously khamenei declared that "executing minors is illegal, if they're virgins". By which he meant that female prisoners are to be raped multiple times before execution. [1]
But I guess that's better than vague oil corruption and evil western influence, isn't it? Never mind that of course the revolution has totally failed Iran. They did not bring jobs, did not bring housing, did not ... in the 50 years they have in power.
Needless to say, more people died in Khomeini's purification than in every other part of the revolution combined. Hell, more people died in the last 5 years of "islamic" peace, than died in the 5 years of the revolution.
