Russia sure as hell wouldn’t have won without all the logistics backbone provided to them by the Allies.....450,000 trucks (they had no significant automotive industry)....2,000 locomotives at a time when they produced 200...etc. Without that there is zero chance the Soviet Union is able to project power all the way into Central Europe. They’d have had the same problem the Germans did once they got too far from their supply bases.
Very little of that arrived before winter of 41 and Stalingrad. The Germans had two or three months to achieve their victory in Russia, but they never had a realistic chance either way. Russia’s too big, Germany was too morally bankrupt, and Germany was too small. But Reich fans always have this lost cause and thinking where they believe the Germans could have done it. The Germans were viewed as Invincible from the first two years of the war where they rolled over pathetically weak Nations. They simply didn’t have the military machine or the ability to take on the Soviet Union, much less the British Empire are the United States
