Poland, Czechia, Hungary,

Which part of Soviet is so hard to understand? The peoples of those countries were never Soviet citizens.

Again... the majority of Jewish people murdered during WW2 by the Nazis were Soviet citizens who were murdered on Soviet territory captured by the Wehrmacht.

The idea that the Holocaust only happened in death camps like Auschwitz is a myth created by western media - which, for reasons that should be obvious to any leftist, never had much of a problem with the Nazis slaughtering millions of people in Ukraine or on the Russian steppes.

The largest part of the Holocaust looked like Babi Yar - not Auschwitz.
