I’ve seen too much of this. No, the nazis and the Soviets were not equivalent.
Do. Better.
ethnic cleansing
Ethnic cleansing is the explosion of an ethnic group from a geographical area. The Nazis did not attempt to ethnically cleanse Europe of Jewish, Romani, Slavic, etc people.
Genocide is the act of destroying an ethnic group via destruction of individuals of that group. The Nazis did attempt to commit genocide against Jewish, Romani, Slavic, etc people.
Yes, bad phrasing on my part. The Nazis attempted to carry out the complete annihilation of those groups, but only succeeded in partially annihilating those groups.
However, the definition of genocide covers attempted destruction in part of a group. For example, killing all the X people in Y city is still genocide.
