trad123, you can't earnestly cite the Nuremberg trials, which were show trials with "confessions" made under and after torture, for anything regarding WWII. It was the victors tribunal, the only possible result of these trials could've been that Germany was wholly and solely responsible for WWII, which is demontstratably a lie.
Regarding Katyn and many other massacres I completely agree with StLouisIX, Russia is responsible for those but of course blamed Germany after, while in reality, German troops and the red cross closely examined and realized with horror what had happened at Katyn when they arrived there during Operation Barbarossa.
