Most Russians have no idea that the Soviets invaded Poland in 1939

Russians and Germans in Poland

Polls among Russian people show that Russians don't know that in 1939 the Soviet Union invaded Poland 17 days after Nazi Germany. That may also mean that Russians don't know that Russia is partially responsible for starting the World War II in alliance with Germany.

Two days ago Russian foreign ministry showed its arrogance by claiming on its Facebook account that by September 17 Poland was in complete chaos and lawlessness when in fact Polish armies were beginning, starting with the battle of the Bzura, to turn events in their favor and might have even pushed the Germans back if it wasn't for what Poles call "a stabbing in the back". It was called that because Poland and the Soviet Union had a signed "Non-Aggression Pact".
