Just as a beginning

It would seem that your point of view that the British were hungry for war with Germany has some considerable opposition and my view is in the majority, which is funny because my views tend to be pretty original and pretty challenging. But the BBC certainly thinks that Hitler enjoyed a favorable view on the whole in Britain, that most thought his territorial demands were just and some even voted not to fight if the occasion should arise. Quite interesting and contrary to your statements.
Even if both of us are only half right, without being surrounded by U-boats and with decent statesmanship by Germany I think there was a good chance Germany could have kept Britain and the US out of the war. This would have made Fortress Europe pretty strong.
Of course Hitler still could have bought the big one by invading the USSR..... He was always one with the ability to snatch defeat from the jaws of victory.
