"The russians beat the germans in ww2" - Russia did tie up the bulk of the German forces. And they suffered and inflicted the bulk of the causalities. So in a sense, this is true. - Regarding the topic at hand, the US and UK literally liberated France. - As others mentioned, Russia was reliant on critical US industrial help. They didn't do it alone. - The US had still not fully mobilized when the Germans and Russians were having some of their largest conflicts. I would argue that the US had not fully mobilized even by the end of the war (e.g., look % of population enlisted, industry still ramping up). Even if Russia had not fought, the US/UK would still have defeated the Germans. If you look at the size of the Armies that could be fielded, the Germans had little chance. Their best bet was to reach some agreement with the US and UK, occupy Europe and focus on the Russians. Having said that, when their opening push against Russia failed, they'd were doomed there also (i.e., once Russia regrouped, they could have defeated Germany alone). - The US had strategic plans to defeat the Germans if both the UK and Russia fell. The size of the planned navy, army and air force proposed was bonkers.
