The Imperial Germans were anti-Semitic, but they were smart enough to know that German Jews were just as patriotic and would contribute to their nation.
Because the Nazis were so arrogant, they drove away potential allies (such as the Ukrainians and White Russians). The Germans who did escape the Nazis became valuable to the Allies.
The Germans wanted to get payback for what the Allies did in WW I. However, the Generals wanted to wait until they were fully mechanized and had equipment and personnel required to win a war...they wanted to start the war around 1943-44.
The Nazis lost WW II on September 1, 1939.
The Soviet Union was going to eventually invade anyway, probably by around 1943.
