Today we know that the German High Command considered valid at the time that the resistance provided during and after the landing, could not be too strong. It can be assumed that the landing would be successful, albeit at the cost of significant losses. Meanwhile, given the resistance of the British, it is unlikely that the British occupation would end the war. Most likely, the British government would continue to fight from Canada. If we correctly judged Hitler, after the successful invasion of England, he would start an attack on Russia with even greater zeal. Huge value of US supplies of materials, which provided an opportunity to fight Russia is well known. After the loss of the British Isles, this support would be very low-key and cautious, because the sea route would begin from the United States. However, if we take everything in general, even the possession of the United Kingdom would not be sufficient to ward off the final fate of Germany. United States's determination to destroy the Hitler regime was too big for that.
