ok.Tonight I am in the mood to play Harry Turtledove. Let's say Hitler was just a bit more lenient and didn't ban the commies. They either take power (not likely), or stay as one powerful opposition. Naturally Hitler would not want to upset them too much, for fear of civil unrest, and so he would stay in good relations with USSR. Not having to attack them, he would not divert his resources to the east, and would manage to conquer England and probably North Africa. The US would not be able to defeat Germany and Japan combined, and most likely it would be attacked by the Soviets as well.
US and their (only) ally Canada will soo be overwhelmed.
Badaboom!
FF a decade and the entire world looks like something out of "1984"
