On the hind sight, it looks to me that Uncle Sam wanted to defeat the germans, and Uncle Stalin, who was between a rock and a hard place, was more than willing to do that job at any cost, but had lost most of his military industrial complex to the advancing germans, and Uncle Sam stepping in with the "Arsenal of Freedom", and saved the day for Uncle Stalin.
For each truck, ship, airplane, machine gun, can of food etc etc sent to Russia under "Lend lease" agreement with Uncle Stalin, saved canadian, american, british and french soldiers lives, and shorten WW2 considerably ?
Do we owe part of our victory over the German, to the 27 million Russians who was killed in action, while fighting the germans, part in with military equipment supplied by the west ?
Would Germany have won WW2, if we had not supplied and replaced Russia's military industrial complex losses to the advancing germans ?
Could the west have defeated the germans, without the help and the enormous sacrifice of Russia ?
Have in mind that the germans, in 1945 were on the verge of developing nuclear weapons, as well as had an advanced rocket technology delivery systems in place, which was stopped by advancing Russian military.
