The issue is what FDR acquiesced to at Yalta. Once the Yalta deal had been cut, yes, it would have been an exercise in futility for our armies to counter the political decision already made.
My problem is with the political decision leading up to and at Yalta. I think it resulted in the suffering, misery, and death of millions at the hands of Stalin who, if you do a body count, was much more vicious than Hitler.
My contention is the opposite. Yalta was the recognition of an already accomplished unalterable fact. The Red Army had occupied Romania and Poland, and was well on their way to occupying Eastern Germany, Czechoslovakia and Hungary. There was absolutely nothing we could do to keep that from happening. Having occupied those countries, and having brought the commissars with them, they were not going to leave short of military action forcing them out. And as we’ve pretty much conceded, that wasn’t going to happen either.
As far as “what if’s” I refuse to violate henkster’s law.
