What if War War Two was against the Soviet Union and not the Nazis?

Could it be possible for the allies to join Nazi Germany to fight against the Soviet Union. Say they are seen as the war mongers and the Nazis protecting themselves and their neighbors by annexing them. How would such a war fare. And what would Japan role be. Would Nazi Germany survive to the present,collapse like the Soviet Union did, or adapt themselves to less totalitarian. What you think?
 
A potential POD could be where the Germans don't invade Poland in 1939, opting to support the Finns against the Soviet onslaught in an ATL Winter War.
 
Fighting alongside Nazi Germany is most likely a nonstarter. However if you make Germany “merely” fascist a la Italy you could probably get the West to back them against the Soviets.

Another possibility is Germany going communist, sparking more fears of the encroachment of communism. This could lead to a World War II pitting fascism and liberalism against communism.
