While Russia would prove to be a more troublesome foe than Germany, I would still see an Allied victory in the end. Russia possessed more armor than the allies and better. Yes the M26 was good, but the IS-2 and IS-3 were better IMO. The T-34 is better than the Sherman. The strong point of the allies is in air power and in combined arms combat. Russia did have good fighters but not enough nor the ability to replace them. Once Russian fighters were cleared the ground attack planes would be easy prey.

This is the point where Russia would fail. All of the armor would now become sitting ducks for allied fighter bombers, supplies and replacements would not be able to reach the front. The original front line divisions would be destroyed and the allies would press forward.

I do not think that it would have mattered that Japan had not surrendered because things were already in place to finish them off without more strength from the ETO. While some units were ordered to prepare to move to the PTO, no substantial moves were made for several months after the ETO was closed.

The Germans at the end were not what they had been several years before but they were still something. Those that were fit would have added at least one million men if not 2, and their equipment was still serviceable to a large degree.

I do doubt that Moscow could have been taken before winter, or if that would have been the target at all. I also wonder how the American and British people would have felt about fighting Russia. After all of the propaganda about how great Russia was would there have been a lot of questions about this battle.

This would have been one for the books though and maybe some one should make a movie about it.
