Patton pushes on (what if)

[Kralizec]

It would most likely have been disastrous. The only way I can see the Allies winning would be if they managed to drop nuclear bombs on many of the Soviets' population centres. The USA managed to do this to Japan because they had near-total air superiority by the time, but the Soviet air force would be likely to intercept incoming bombers.

Public opinion wouldn't approve of backstabbing an ally that way, and nor would they like the prospect of another war with additional millions of casualties.

Just like paratroops, I think strategic bombing would have become cost ineffective. Russian cities were already bombed out and the industry gone...

Paratroops were considered cost-ineffective? I recall reading once that Hitler discontinued the use of paratroops after a particulary bad experience with them due to misuse (in Malta, I think) but that some speculate that they could have been of great use on the eastern front, especially in the early months.
