This quote by Heinrich Himmler – the SS Reichsfuhrer and de-facto head of Nazi Germany security services – is another proof that the Nazis did not intend to exterminate all Jews in all Germany-controlled territory prior to the invasion of the Soviet Union on June 22nd, 1941. In other words, they had other – not nearly as murderous – ideas about the “Final Solution of the Jewish Question”.
The Soviet Bolsheviks began to commit their first acts of democide (physical extermination of whole social groups) during the Russian Civil War of 1918-22. There were two subsequent waves of democide and genocide in the Soviet Union – during the infamous “collectivization of agriculture” in early 1930s and during the “Great Terror” of 1936-39.
Keeping such massive-scale murder was impossible and the SS had more or less competent foreign intelligence service so Heinrich Himmler was well aware of these enormous crimes against humanity.
