Hitler was NOT too weak to conquer the Soviet Union. Hitler just did some heavy miscalculations, one of which was to assume that Stalin wouldn't send millions as cannon fodder in Stalingrad; and he he had too huge an ego to let his generals handle the operation. Hitler was very smart as far as managing lower level combat, but he knew little about total army movements and macrostrategy.
Hitler had no plan of engaging the USA into it. Hell, he didn't even want to engage Britain in it. Britain engaged in it herself in defense of Poland. Hitler had always dreamt of an alliance with Britain (read about Ribbentropp's activities in England and read Mein Kampf) and didn't care much about overseas colonies, accepting the British empire as part of global culture.
I would love to see some evidence that Hitler wanted to drag the USA into a war. Sounds very far fetched to me.
And this is coming from a Sephardi Jew, not a Nazi apologist.
"Hitler had always dreamt of an alliance with Britain (read about Ribbentropp's activities in England and read Mein Kampf) and didn't care much about overseas colonies, accepting the British empire as part of global culture. "
You are right on - few realize that Hitler rose to power as an anticommunist , stemming from the hundreds of thousands of mennonites and fundamental germans that were killed in the famine genocides of 1921 and 1932. His cult creed also demanded "Livingspace" that lay to the east (not the west).
