I was replying to the part of your post that claimed the US saved Europe in WW2,
Germany had pretty much kicked most of Europe's ass before they got into it hot and heavy with Russia. As you can see by highlights below Germany did not attack Russia until after Europe was little threat themselves. If it had not been for the U.S. Germany would have just continued to bomb the U.K. until they were totally beaten into submission.
German subs basically controlled the shipping and sank most of the ships bringing in war supplies that the U.K. and Europe needed.
Again it was the addition of U.S. naval forces in the Atlantic that did a lot to turn that tide of the German subs control as well.
It is always possible as well if the U.S. had not gotten involved and not only their manpower but their much needed on the battle lines equipment of war had not started turning the tide on the western front in Europe that Germany would have been able to put more focus on defeating Russia changing that outcome as well.
Actually the AXIS mistake was Japan attacking the U.S. and getting them actively in the war.If Japan had of been smart instead and attacked Russia from the east from the lands they had conquered in China while Germany engaged them from the west that Russia with the lack of goods and military weapons and hardware needed to fight a war then Russia probably would have been in trouble.
But regardless I think the time lines pretty well back up that the tide did not turn in Europe's favor until the U.S. put boots on the ground, planes in the skies and equipment on the field in WW2.
And this was in addition to while we were at the same time fighting the Japanese in the Pacific theater which also kept Japan out of the Axis war on the European front.
