At the end of the day, these are still Japanese writers who are throwing their own bias and filters on stories from around the world. Often times those stories are filled with smear campaigns, propoganda, literal rewrites to disparage the loser and exhalt the winners of bloody conflicts and atrocities, fabrications, accounts with missing portions filled in with historian speculation, etc.
Humanity itself is inconsistent, and sometimes we enjoy what comes from it and sometimes we don't. Perception trumping the truth is also a thing in real life too.
