Right, you just said that the leaders of Germany, Japan and the USSR made "plundering, torture, murder, and rape" a matter of official policy and everyone followed, whereas the United States took the high moral ground, and any such "plundering, torture, murder, and rape" would merit "stern disciplinary action," things like "until every murdering Jap is wiped out" notwithstanding. Go democracy!
There's value in illustrating the various evils and atrocities of any civilization--I can probably name just as many American and British atrocities as you can, beginning with the treatment of my own ancestors. This doesn't extend to whitewashing the truth about other civilizations' atrocities. I was making a strategic argument about not mistreating those who surrender to you; you're trying to make some argument that Hitler and Stalin were nice guys who never at all mistreated people in occupied countries. Respectfully, I don't think I'm the one with a nationalistic axe to grind here.
Stalins artificial famine in Ukraine was official policy: http://en.wikipedia.org/wiki/Holodomor
There is no need to point out Germany's official policies of genocide, as they are well recorded and attested to in the historical record.
