I mean we did okay-ish with japan, and that was in the immediate post-ww2 period. There was a bunch of gaishas for a while that were complaining (iirc) about sexual assault from american troops, the nation immediately in the postwar period was fomented with a ton of nationalism and we didn’t really do a great job of undoing that. Though, their trajectory nowadays is pretty good, and it’s not like you can really blame all of that on the american occupation, really.

South korea, though, even though I don’t know as much, I’m pretty sure we fucked up that one, since that war basically never ended and nowadays the country is a late stage hypercapitalist hellscape where plastic surgery to make you look more western is incredibly common along with the prevalence of cults and a wealth disparity that’s pretty US-adjacent.

So I dunno if we did super well on those. Probably better than, say, Iraq, but I think our trajectory overall has been on a pretty consistent downwards trend since ww2.
