And FDR let the Russians take a pounding at the hands of the Germans and without that strategy, the Russians would have gone deep into W Europe after the war.
Actually, Stalin signed a Pact with Hitler in 1939. Hitler stabbed him in the back in 1941, though they both invaded Poland in 1939. Stalin provided trainloads of war supplies to Hitler right up to days before Hitler invaded Russia in ‘41. Churchill and others warned Stalin, but Stalin didn’t believe them. Hitler did kill many people in Eastern Europe and Russia in a genocidal conquest. FDR, as soon as he could, aided Russia with all types of war equipment. Russia did go deep into Western Europe after the war; they were in Berlin, after all, Czech (remember 1968?)and Hungary (remember 1956). It was a communist ploy to call all of Central and Western Europe Eastern Europe without regard to geography or historic reality. This was done to make Soviet/Russian control over these nations seem all the more natural. But the nations held by the Soviets behind the Iron Curtain were mostly central European ones. Yet Marxist and commies called the captive nations Eastern Europe. Liberal Democrats did too. I see nothing crafty, prescient, or cunning in FDR’s policies. He was if anything the most naïve US President whoever dealt with the Soviets or “Uncle Joe” as he called the butcher Stalin. Roosevelt was very much like Obama in the sense that both of them believed their own charisma would make criminal tyrants swoon to them and bend their ideology.
That's the Soviet propaganda version of WWII. The truth is D-Day was a massive operation that could not have been achieved any sooner than it was. We fought the Germans where we could as soon as we could, starting in North Africa and Italy. We also had to put massive resources into the Battle of the Atlantic, and the air offensive against Germany (not to mention Japan). And the reality is that almost exactly half of Germany's armed forces were deployed on the Western Front, from Greece to Norway, from late 1942 on. We also provided the Soviets with aid, especially 2.5 ton trucks. Without those trucks the huge Soviet offensives of 43-45 would not have been possible.
