I saw this video by a guy called alternative hypothesis make an interesting argument, that had germany allied with turkey and taken baku the soviets would have collapsed. Also if they took moscow they might get negotiated settlement.
I think they way they could have won best is if they had done diplomacy around danzig better, then maybe never go to war with the western allies and smash global communism instead
Yeah I saw that video to. The chances of winning skyrocket however the thing about this is russia still isn’t like France where taking the capital would knock them out. I would still try to add other things that would increase the chances but yeah this is arguably the best buff the Nazis could get
If the Germans were able to secure Britain by either successfully completing Operation Sea Lion or Lord Halifax succeeded Churchill as Churchill be forced to resign due to his refusal to make peace with Germany and then Britain's signs a White Peace Deal with Germany. The Germans if they were able to invade or secure an alliance with Turkey would been able to invade the Caucasus Mountains securing them and the Oil Fields there effectively cutting off Oil from the Soviet Union. Then the continual advance from the Eastern and Southern Front to push back the Soviets past the Arkhangelsk–Astrakhan line (A-A Line) into Central Asia then the Germans would secure and consolidate their newly conquered territory of European Russia and then eventually resume the push into Asia over time.
If Japan had turned some of their forces north and took Vladivostok during Barbarossa it would have been over. I doubt they could have "won" but they could definitely get a peace treaty with Britain after.
