Answering OPs question, the USSR is likely to have a whole united Germany as part of their communist block alongside eastern and Central Europe given they would eventually defeat them but they wouldn't try for a communist Italy or France for instance but definitely would help the local partisans, combine that with more and more German and axis troops being thrown into the Soviet meat grinder, means the rest of allies can try their own smaller version of D-Day to liberate France and then do a negotiation with Italy to end the war, without the USA to mediate things, Allies can't deny Stalin the whole of Germany in exchange for not inspiring communists in Italy and France. Meanwhile they take their armies and go on to directly fight Japan and ensure Mao's guerrillas will win in China which sends Japan in panic mode allowing for the Brits to steadily push the Japanese out of Asia, given the US won't be there too, it means a United communist Korea and possibly communist Japan or at least, one defeated in their conquests and forced to the negotiation table.
USA would still have a very good but not as good economy as they had otl post ww2, so they would still be willing to ally and do their own version of the Marshall plan in Western Europe, plus with the atomic bomb project not being needed ASAP, it would have some effects on how exactly US anti communist policy would go
