i defolently think that lend lease had a profound effect on the russo-german war! I think the things that helped most was...clothes,food,MONEY from our government, trucks, ammunition. The huge amounts of material we gave them helped them a great deal i think and the war would have lasted longer had they needed to find that stuff on their own. Things like aircraft and tanks they would have been fine without. Especially Tanks...HA things would have been better if they were giving us tanks!
