If for some reason Nazi Germany did not launch Operation Barbarossa, would it be conceivable for the Nazis to begin buying or being loaned Soviet armaments? Panzer divisions equipped with T-34s and all that. How would Britain (and later possibly the USA) react? What kind of concessions would Stalin try to extract in exchange? How desperate would the Nazis have to be to accept aid from their worst enemies? My understanding is that Germany was using raw materials from the USSR to supply their war machine under the terms of the Molotov-Ribbentrop pact, but how can this be expanded?
