Unfortunately the anti-Japanese folks are the loudest in the room and loves to manipulate online opinions that that is the mainstream consensus.
They don't pause to ask, who benefits from this manufactured crisis that is aimed at driving a wedge between Korea and Japan in particular, both close US allies.
I'd actually say that's a decent corollary versus counterpoint. The folks you attack will hate you. Regardless of whether you genuinely change. But we aren't directly attacking our allies right now. The folks who weren't directly war crimed by Japan, e.g. South Asia, have moved along just fine.
Not to mention the tariffs against our allies we levied. Or the fact we personally insult them from our highest office WRT things like calling their dead service members cowards.
They're not going to just forget how the US population and half it's legislative body just... Doesn't care at all. Will just let all of this happen.
We have become an apathetic, unserious people.
It's not like America was super popular before all of this, it was more tolerated then celebrated. This very large straw broke the camel's back and everyone is working on moving away and after that's done, why come back?
