So FWIG, the first several years of nuclear weapons development in the USSR were hindered by a shortage of uranium within the country, which would remain the case for several decades; as such, the vast majority of nuclear material in the Soviet program came from their conquests in Eastern Europe, specifically Germany, Czechoslovakia, Bulgaria, and Poland. If the Red Army had done less in the war, and as a result fewer uranium mines are found east of the Iron Curtain, how does that affect Russia's ability to create a nuclear weapons arsenal that can compete with the United States?
