I've seen that too. But what would the goal have been? To destroy the Red Army? To take Warsaw? To take Moscow?
With limited aims, the Western Allies probably would have won, mainly because of their superior air power. Even then it would have been a bloody mess.
To push Russia back to their 1938 boundaries, saving Europe and keeping us from facing the massive Russian war machine for generations into the future.
How different would America and the world be today if not for the Russian/Nazi alliance of WWII, and the Russians succeeding in empire building beyond their wildest dreams.
The only argument should be whether it could have been done, not whether it would have paid off.
Odd that international communism gained half the world under our socialist, ‘president for life’ who held the presidency through election after election, after election, and election, until he finally died in office.
