Really, you're going back to WWII and the Anglo-Soviet invasion? Why not go back to the 19th and The Great Game?
https://en.wikipedia.org/wiki/The_Great_Game> Both the US and the UK have manipulated power in Iran in the past multiple times. https://en.wikipedia.org/wiki/1953_Iranian_coup_d%27%C3%A9ta...
I'll tell you a secret; it wasn't just the US and the UK but several other powers. And not just in Iran but all over the world. There was this little thing called the Cold War as a backdrop, from your own link:
"The British soldiers withdrew from Iran after the end of the war. However, under Stalin, the Soviet Union partly remained by sponsoring two "People's Democratic Republics" within Iran's borders."
> Even the Ayatollahs themselves are in power now because we thought regime change is necessary in Iran, hence we did aid their revolution.
So? What do you imagine this magical aid was? There was quite a lot going on in that part of the world at the time: https://en.wikipedia.org/wiki/1973_oil_crisis

I don't know who we is supposed to be, but if you mean the US, certainly it had interests and influence it tried to wield. Very unsuccessfully. Quite an interesting unsavory story to be sure, but scratch beneath the surface and you'll find a quite complicated one as well - it isn't black and white at all.
Iran never had democracy, it is cursed with oil as you point out and geography plays a role as well, as does religion, welcome to how the world actually works.
However Iran ended up with Ayatollahs, one could only ever so gently suggest that perhaps Iranians themselves had some agency and responsibility in this matter, or how North Korea ended up with the Kim dynasty - hardly a reason to be an apologist for these dangerous repressive regimes.
