White washing Soviet aggression

I just shook my head when I heard the narrator describe the Soviet invasion of Poland in 1939. After showing how the Nazis invaded Poland from the west,north and south, he said that the Soviets "took up positions along the Bug River" and of how the Germans had to decide whether to keep going or quit, so they quit. Nice white wash of our genocidal Communist allies.

In fact the Soviets INVADED Poland from the east and split the country with Hitler in accordance with secret provisions of the Molotov-Ribbentrop pact. They were joint aggressors with the Nazis in invading Poland. Nice try at a save, Capra,but it didn't work.
