These countries were not thriving democracies. So saying "if it wasn't for the US, these people would be living in a democracy" is false.
The options are basically US-aligned dictator, or USSR-aligned dictator. I see no issues with the US supporting the first.
Anyway, you don't know that these are the only two options. You don't know that the USSR would've installed dictators like the US actually did, though I consider it unlikely as there's no evidence they even tried.
It's a textbook example of it, just like this follow up. But I expect nothing else from a user that for years and years always, with no exceptions, no matter the subject, sides with wealth and power. Utter contempt is all I have for you.
