Well, yeah, the earliest sources were White People hiding in the Foreign Quarter... You seem to be stuck with a western centric view of history. Which is why we don't treat the Japanese genocide in China as harshly as we treat the German genocide in Europe.
But there's a reason why China and Korea panicked when the late PM Abe started talking about remilitarizing Japan.
Actually, he's revered in China because he took his country from being a backwards medieval economy to one of the world's super powers. Which is why you go to bed every night peeing your magic underwear about the Chinese.
Same thing with Ho. Americans see him as a demon, but Vietnamese see him as a national hero who fought French, Japanese and American invaders.
Now, I used to work with a fellow from India, and a discussion about history came up, and he referred to Churchill as "That bastard". From an American POV, Churchill was a great ally, from an Indian POV, he was the bastard who killed millions of Indians through Famine, sent millions more to die in the war against Germany and Japan, and then tried his level best to double cross them on promises of independence.
Which is a key thing you need to take away from this. NOBODY likes a foreign invader, whether it be the Japanese slaughtering Chinese to a Mexican offering to clean your toilet for cheap.
