The Katyn Massacre is a major Communist atrocity that puts the focus on the Soviet Secret police, the NKVD (later the KGB). That organization was headed by a series of Communist Jews and most of the worst butchers were Jews. Communism was Jewish from its beginning to its end. I would not be surprised if the grandparents of many present-day Israeli politicians were wearing commissar uniforms and shooting defenseless civilians and POWs in the head as part of their daily routine back in the 1930s and '40s. Look at the endless Jewish news media focus on the rat-faced lesbian, Anne Frank who died of typhus (not "gassed"), whose "diary" was a piece of fiction written after the war with a ball point pen. Meanwhile, the family of Tsar Nicholas II gets virtually no mention even though militant Jewish communists butchered the whole family including the little girls. That's the sort of "mercy" Jews show Gentiles when they have dictatorial power.
