That isn't correct at all, fdr gave the soviet Russians billions in war material that was used to facilitate communist's eastern front victory. If that war material wasn't given to the damn soviets by the commie sympathizer in the White House, who are just as evil as the Nazis, the two would have fought to a standstill and eastern Europe would have been spared Soviet occupation for forty years.
Or the Nazis would have won.
I suppose that would have been a better result for the people in Eastern Europe, in your opinion?
