I'd say both Jap and German war machines were equally savage to combatants and non combatants. Murdered millions of innocent folks. War is not all glory, many die that are never known or found.
wrong again........ The Germans (other than the Jewish people) were no where even close to the Japanese. The Japanese killed over 300,000 Chinese just looking for the Doolittle Raiders. The were countless people gathered up for chemical experiments and many complete towns completely destroyed (people included) throughout China. Did Germany have a Battan death march? Errrr NO! Was every prisoner taken by the Germans starved into skeletal form ? Errrrr NO! I could go on but don't feel I need to.
The Russians (our Allies) had 30million people murdered. Read up on how many German survivors came back from Russian captivity. Erich Hartmann was held for 10 years after the war ended, what the hell did he do that 10 years of hard labor required? I'm sure if you totalled up the civilian death toll that the German and Japanese civilians suffered there were probally more civilian loses than the total American military loses. I think that a little light WW2 reading would bring you up to speed.
