Yes, Zorak; I was responding to previous posts about World War I. There's little doubt that without US involvement in the Second World War, the map of Europe would have been rather different. Britain may have kept its independence (that would largely depend on whether Britain still received material assistance from the US through Lend-Lease etc.) and if it had, would probably have eventually have had to sign a peace treaty with the German Empire.
Hitler would still have gotten bogged down in Russia, I think. Without American assistance to Russia, they'd have had it a little harder, but I still don't think it'd have been a walk-over for the Germans. Possibly it would have ended in a World War One-type bloody stalemate, or perhaps the Russians would eventually, with an even more incredible loss of life, eventually turned the Germans out of Russia.
Then there's the question as to whether the Pacific War would have still happened. Quite likely. Japan didn't attack Pearl Harbor out of solidarity with the Germans; they did it to cripple US sea power until their conquests were a fait accompli. Perhaps, if the Germans hadn't pre-emptively declared war on the US in solidarity with the Japanese, US public opinion might have decided against a European distraction. Who knows.
History what-ifs are fun.
However, what I was ranting about was the American notion that, because the US was instrumental in turning the tide of the European war in 1942-45, the First World War must have just been a prequel with the same dynamics. And that the rapid conquest of France in 1939 was entirely due to French cowardice, which must be a historic, and doubtless genetic, trait of the French.
What happened to France in World War 2 can be entirely explained by the experience of World War One, the devastation it wrought, the death toll and injuries it caused. France wanted to make sure that any future war didn't occur within France itself, so it put all its resources into defensive works, e.g. the famous Maginot line, and encouraged its neighbors to do the same. Unfortunately those smaller neighbors didn't quite fortify to the same degree.
And once the Germans had bypassed the French defenses, it's not entirely surprising that France didn't decide to die rather than admit defeat, given the slaughter of the last War. At that point, defeat was inevitable. The French had had their fill of death, and unlike the British and Germans, the horrendous death toll of the First World War happened in their own country, not in some foreign land. They got to see it first-hand, got to bury the dead and try and rebuild the destruction.
