Nice thought but US industrialists helped stalin create his industrial base in the 1930s. Vast quantities of US arms flowed into the soviet union during WWII to help Stalin win the war in the east. Stalin’s men fought bravely. But they could not have won without American weapons and supplies.
In addition, the US fought the Germans in the West and the Japanese in the East.
And the Japs wanted no part in helping Hitler against the Soviets.
