@dave @LukeAlmighty Germans were not mass killing Jews prior to the opening of the war. Germany between 1933-1939 only had one incident that historians claim was program which was the night of broken glass. Which Wikipedia claims only 91 were killed if that.
The Germans were denied a merchant fleet and food after 1918 until they signed Versailles. This deliberate act starved hundreds of thousands.
There was no genocide of Jews prior to a genocide of Germans (or after). The Germans fought liberal Jews in the west and Bolshevik Jews in the east to prevent thier own people from being strangled between the two.
Once war is declare between two people's the resultant killing is not a genocide. It's war
