To be fair, I grew up with this shit too, and while I refuse to denigrate public education, the degree to which our curriculum is manipulated to tell a particular story from a particular point of view is hard see as anything other than indoctrination in hindsight. It takes a while to mentally pull oneself out of that sort of thing, particularly when it occurs in our formative years.
But also: there have been a number of disclosures and revelations about the history enumerated in the post you replied to in the last decade - for example, the whole saga around the Iran Coup, and how it was largely instigated by BP (of deepwater horizon fame) and essentially occurred because the Tehran CIA station chief basically stopped listening to orders from DC to back down and yolo’d the fucking thing. That’s not to say the government at large is blameless in that particular case, but it was WAY more complicated and fucky than most people realized until very recently.
