Heres a map ive been working on for a few days. I know its not as impressive as half of the stuff on this site but im just trying to get some comments on how to make it better.
Basic POD: Hitler has a moment of sanity after Pearl Harbor and doesn't declare war on the US. The US Congress, being hyper-focused on Japan doesn't declare war on Germany. WWII turns into USA vs. Japan ((obvious winner USA)) and the USSR vs the Nazis ((not so obvious winner USSR)). And thus the Soviets take over all of Europe with no Allied D-Day to stop them.

Basically everything that is some sort of Red or Pink is Commie.
