I know this topic has been discussed before, but as we all know, the search function sucks. So I'm here to bring up Lend Lease again. We know the purpose of Lend Lease was to provide war materials to the allies in Europe, first with the UK, and later to the USSR. These shipments, especially those to the USSR, were supposed to be only war materials; guns, ammo, etc. However it turned out that much non-war material was being sent to them, in particular the Soviet Union. Things such as food, copper wire, building materials, and luxury goods were being sent. It is also known that the Soviets also got atomic weapon secrets from Lend Lease, which is why Stalin wasn't surprised when Truman said the US had them. The state department did not want to send the USSR materials that could be used to rebuild the Soviet Union after the war, given our anti-communist policy. So in reality, the USSR was only kept afloat by donations from Capitalist countries.
Now I ask what if Lend Lease either was given to the soviets, or that no non-war materials were sent to them, only guns and ammo? What would happen to the USSR after the war? Without having the necessary materials to rebuild, how would the Soviet Government be able to handle all of the refugees? Could not having the materials necessary to rebuild after the war lead to a revolution or civil war?
