France wouldn't have fallen sooner or later with or without US's supplies and intervention. Nor would the US help to discourage the Germans from embarking on the risky Operation Sea Lion. What the US did was hasten the inevitable downfall of the German Reich by creating a Western front. War Games done after the war have largely conclude that the USSR vs Germany would've ended WW2 by themselves but at a much larger casulty on both sides. Germany was on the verge of economic collapse already

USSR had deal with Germany, they invaded Poland at same time. Funny how history is written by the victors and today they are considered as good guys of ww2.

Even US autors like David Glantz dont agree with your statement. Lend-lease didnt came to USSR in sufficient quantities to make the difference between defeat and victory in 41-42. And later on it only hasten Nazi demise, war in eaatern front would be prolonged for 12 to 18 months without it, but Red Army would crush Wehrmacht in any case.
