But you surely see that Hitler was not interested in invading England. At least until England's declaration of war ? Thus he certainly had no real infrastructure and military for such a strike.
(Even Doenitz had said, remembering WW1: "Why does this have to happen just of all to me, again?")
Hitler was not interested in declaring war on England either, indeed he did not quite understand why England did it to him.
Because of Poland ? Why didn't England also declare war on Russia then ? After all, Russia and Germany had divided Poland between them, and was then attacked and invaded from both sides.
And what about what Russia did to Finland ? The winter war ? Didn't even US volunteers fight for Finland with Germany against Russia, before the english declaration of war?
Hitler had just hoped he would be able to get through with it, as with those other countries before. High stakes, but etc. blahblah..
Hitler's real and only plan was to wage war against the Soviet Union, and for that Poland had to be invaded for marching through - all else happened because of England's declaration of war, from Denmark, to Norway, to France and so on until to a world war.
