Sir, you cannot prove a negative. Conjecture at best.
What happened, happened.
The fact is the US was the impetus and mass effect that won the war and liberated Western Europe. Another fact was the Nazis/Axis were confronted by two major opponents.
More than one US general thought the logical conclusion would be war with Russia to liberate Eastern Europe- they were military men. The politicians sliced and diced E Europe to placate the Russians, the Poles wanted nothing to do with that plan, among other ex pats.
I take nothing from the Russian serviceman/woman as far as the war against the Nazis go. After that, they became our enemies and the forced occupiers of formerly free countries.
Indeed, I learned that the Russian citizen was taught that the US were the villains for occupying W Europe- that they were protecting Russian territory from the mad Americans who wanted Siberia or something and I was one of them! (FRG 84-87). Viewpoint and disinformation I suppose.
Happy New Year and Peace to you and yours.
“I take nothing from the Russian serviceman/woman as far as the war against the Nazis go.” That has been my point all along.
