American Ignorance of the Soviets in WWII
The result of this ignorance was that we gave them all of Eastern Europe, to do with as they pleased – much to the distress of people in those countries – especially the Poles, who had fought with us bravely – only to be abandoned to their fate.
If FDR had any understanding of the logistics of war – which he certainly did not – he would have given them just enough aid to drive the Germans off their soil – and no further.
At Yalta, where all this was settled, FDR was a dying man – barely able to comprehend what was going – and Stalin was in his prime, determined to take advantage of the Allies any way he could, which he always saw as fools he could deceive easily.
America knew nothing of Stalin’s atrocities - which were even worse than Hitler’s.
