Ok.One vs. One I think that in 1939 Germany could have crushed the Soviet army,but i dont think they could have occupied whole of the Soviet Union.My personal wish for the outcome would have been that they would have exhausted eachother and fought to an standstill.I believe that the outcome would have been a negotiated peace, because French and British would have attacked Germany on her back if it would have seemed that The Soviet Union would have collapsed.
