If there was a holocaust there would have been documented orders in writing from the Nazi human experimentation twin experiment demon portal owning whatever the fuck the NSDAP supposedly were to these creatures on Reddit that still think the holocaust was real.
Up until Nuremberg it was a full defense to say you were following orders therefore any German (or Ostbatallion POW turned German soldier) that was ordered to kill Jews would have got the order in writing and would HAVE KEPT THE WRITTEN ORDER. It was only after Nuremberg that following orders was no longer a defense in war crimes trials.
What this means is that we would have paperwork signed by NSDAP leadership stating that individual soldier such and such, of such and such battalion, is ordered to kill such and such Jews at such and such location and the soldier doing the killing WOULD HAVE INSISTED on having that document before they kill anyone because at the time they would have expected it to be a full defense if they were charged with any war crimes.
For that reason THEY WOULD HAVE KEPT THE DOCUMENT not destroyed it. Why? Because it would hav been perceived, based on contemporary war crimes laws, that such a document would be a get out of jail free card. Remember it was Nuremberg where it was established that following orders is not a defense. Before that time, a soldier could show a written order to do something and walk free from responsibility.
No German soldier accused of war crimes ever produced a written order from NSDAP leadership ordering them to carry out those war crimes. Said war crimes didn’t even exist anyway. There are no corpses in the mass graves at any of the so called extermination camps which were in reality transit camps.
No, the dead was more than real. There are was a lot of dead on both sides. Thing is that overhelming majority of them was not Jews.
Jews was not the main victims of that war, nor in absolute numbers (it was Russians), nor in percentage from whole etnicity (it was Belorussians).
While Stalin was alive there was no such thing as Holocaust in USSR discource. Jews losses was not accounted as something worth special attention. IDK, if Stalin just didn't want to make Russians who suffered largest losses angry or he still fight against Jews in Communist party, but nothing special about Jews and WWII existed. War was officially named Great Patriotic War, not some Jews Saving Operation. Only after Khrushev taking power, numerous propaganda about all that holohoax crap and that Jews losses was somehow special. began to pop up. That is connected with great Jewish influx into MSM. Interesting, that when Brezhnev replaced Khrushev, such preferences for Jews in culture was somewhat cut. State Central studio of documentary movies even made a long documentary "Secret and Explicit (The Aims and Acts of Zionists)" (Тайное и явное (цели и деяния сионистов)). Which is in modern Russia is in a list of extremist materials. :) You could see it here - https://archive.org/details/the-secret-and-explicit-goals-and-deeds-of-the-zionists with English subtitles. Take a look, it worth it, and you will get some clue of how USSR view Jews and why USSR was so hated on the West.
