You're joking, right? The Katyn Massacre is unanimously accepted to have been committed by the Soviets so much that they didn't even dare bring up the accusations at the Nuremberg Trials and the Russian government accepts that they happened under the NKVD. The Soviets had every reason to murder the Polish officers who were a threat to their planned regime. We further have private written records from Nazi leaders which show that the massacres were not ordered by them.
Goebbels diary wrote:‘Polish mass graves have been found near Smolensk. The Bolsheviks simply shot down and then shoveled into mass graves some 10,000 (sic) Polish prisoners.’
