You really want to make the case that America of all countries has clean hands and a clean conscience in this dirty enterprise called war?
Do you mean that when a huge undertaking involving actual, you know, human beings taking action in opposition to a monstrously violent totalitarian regime sometimes involves some of those human beings doing assholish things
There is still hatred towards the Japanese over what they did
Right. Because that's what they (the country of Japan) set out to do. Cruelty and torture and rape weren't the actions of a few idiots/asshats in the Japanese army, those things were the stated tactics, the official policy, from the top down. That wasn't assholishness by abberration, and prosecuted (a la the WV guards at Abu Ghraib), that was marching orders. Your need to confuse the difference between that, and things like what Japan systematically did in China, shows you to be either completely misguided, or simply trolling. The latter, most likely.
