That was fun.
We would have won especially if we fought defensively and bled the Soviets. The idea that they would be able to move over 100 km per day is a bit unbelievable, not because of terrain but because their supply lines would have been under constant air assault. The US could have brought carriers into the Black Sea to attack the southern Soviet Union where they had their oil fields and cut them off from the Ploesti fields in Romania. Also the Ukranian wheat fields could also have been attacked and the Soviets would have lost their breadbasket along with their US food source. Starved of fuel and food the Soviets would not be able to sustain their forces in the field. Under the scenario, after the Soviets retreated to try to defend the Rodina, they would have been within reach of heavy bombers as Allied forces put pressure on the front and the Soviets are starved of food and supplies. Then Leningrad and Moscow both would have been within range for atomic bombs.
The video, which was entertaining concentrates on war materials logistics but forgets an army travels on its stomach and the Soviets would not have been able to feed themselves especially if the US decided to firebomb the wheat fields as well as the oil fields.
