Take the Soviets out of the war and transfer all those German divisions to the west and see who wins.
People like to rewrite history because Stalin was just as big of an asshole as Hitler.
The people in the Soviet Union were brave people and many of them died fighting to stop the Nazis. The numbers of deaths they occurred was major.
I think this is often not realized by many Americans. We've never suffered those kinds of losses. WW2 left a lasting scar on the Russian soul. Their towns and cities are full of statues and monuments testifying to this. Military losses were estimated at over 8,800,000 and civilians 13,700,000 or more killed by the Germans through war (including genocide and reprisals,) died from hunger, disease, lack of medicine during the occupation, or died in German forced labor camps. During the 3-year seige of Leningrad, 1,500,000 died from hunger.
I don't think it's possible for most of us to concieve of those kinds of losses. The bravery of those people, and what they lost should never be diminished for political expediency.
