@Karl7:
All interesting points, and I will only add this:
It seems odd to me that Germany would not have driven a harder position regarding a negotiated settlement with the UK after the fall of France. I know there were some tepid efforts that went nowhere. But what if Germany delivered an “inverted ultimatum” in which Germany declared it was going to unilaterally conclude a final peace treaty with France and then withdraw from France. (Albeit France would be under a right-wing, Vichy-ish government.),
What would UK have done? Said no? The UK people would have continued supporting a war government that was going to “reinvade” France? The US would have been off-footed too. The UK would no longer been under threat, taking the wind out of the US interventionist sails.
I think such a deft move would have thrown the UK off balance. Why go on fighting after a bruising loss when the enemy is ostensibly giving up its gains?
True Italy would have been a problem to get to go along given they were losing their colonies, but if I were Hitler I would have said, “tough luck.”
My understanding was the Hitler never intended to “conquer” the west, just defeat them so as Germany could move eastward without a potential 2nd front in the rear.
I like your point here. Perhaps more of an effort to end the war in 40 would have been the best way to go. I am not sure if Hitler would have turned unoccupied France into a Vichy like system. I think Vichy was created because France was Germany’s west flank and it had to be protected. Because Hitler was so into revenge for WW1 I think he would have set up reparations for France to pay and limit their military had Britain agreed to end the war.
While I agree that is the least intrusive as far as German/Nazi mentality during the war, Hitler was a stupid gambler.
It is a dumb game show, but if you have ever watched “Deal or No Deal”, you would know it is a game of chance about really dumb people (usually) going for the big money even though the math does not add up. Their greed gets in the way, and they fail. I don’t think Hitler had it in him to stop in 40. He was just too dumb.
