If Nazi Germany invaded the Soviet Union before it invaded the West what is the likely hood of a Western intervention? And if not what is the likely hood of a German victory?
I have yet to ever receive an in depth answer to this question so hopefully someone can provide an adequate response with sources here.
The main reason the east and west allied was out of strategic necessity after both sides were dragged into the war. Specifically the west was invaded before the east. However, given the ideological differences and apparent disdain for the east among many western leaders. Would a western intervention have ever occurred if Nazi Germany invaded the USSR before turning to the West? And if not, would this had resulted in the same defeat, an armistice, or possibly total victory in the east for Germany?
Of course one must account for the invasion of Poland and the Polish Guarantee but given the west's response in real history, or the lack there of, I suspect this is a non-issue in this scenario but I'm open to hear what you all think.
