I'm always tempted to see a Soviet/British victory in WWII and I agree, without the United States, it's likely to end up with the Soviets controlling a lot, lot more.
I'd say ALL of Germany, Denmark, Greece, Austria as well as OTL countries. Italy will go communist in an election (say). France will not. Personally, De Gaulle has enough force of personality to prevent that. The Low Countries and Norway should stay democratic due to proximity to Britain and likelihood they would invade first.
Oh, and Doug's full TL attached.
