This isn't about reparations or whining - it's about equity.
You're not supposed to be able to profit from crime.
I wholeheartedly agree! Unfortunately the Cold War mitigated the punishment dished out to Germany and Japan (though Germany was divided and Japan disarmed). And I'm not saying that we could afford to ignore the Russians and let the Axis Powers have it full tilt, but I imagine that Germany and Japan would be far more rehabilitated (and Japan is still a notorious revisionist nation) had we not had to switch to opposing the Russians so suddenly.
Of course, Germany and Japan were certainly punished more than Russia ever will be, and that's not just either.
Japan basically went almost unpunished (culturally) after the war. Germany was definitely punished—to the point that many Germans today feel as though they are somehow responsible for what their ancestors did.
