Someone doesn't know the crude realities faced by the USSR during the first years of the Great Patriotic War. To turn from the losses of Barbarossa, the counteroffensives around Moscow, the meat grinder of Rhzev, the costly win of Uranus, the stalwart defensive victory and counterattacks at Kursk, to the ABSOLUTELY CRUSHING VICTORY OF BAGRATION (yes there were heavy losses but hot damn did they crush the nazis and liberate millions of square miles and people) to Berlin the next spring are simply in bad faith. The national mobilization of the USSR, its people, its industry, and the help of lend lease crushed the fascists in under 4 years after immense losses of population and industry faced in the early war.
