We all know about Hitler's invasion of the Soviet Union, how it took place at one of the worst times for the Red Army and how far the Whermhacht got. But lets say that Hitler is forced to delay Barbarossa for whatever reason.
Perhaps he attempts to carry out Operation Certain-Sea-Mammal(that he fails really does not need to be said), perhaps he devotes more resources to Rommel, or maybe the Balkans Campaign goes worse for him.
Let's go with that last one, as it allows much fewer butterflies.
So, due too whatever issue in the Balkans, Hitler has to delay Barbarossa for a year. Obviously the consensus on this forum that I see is that the Red Army will be much better off.
Could this scenario see a Red Europe?
