How did other countries respond to reports of the genocide?

They ignored all White genocides such as the Bolshevik Holodomor caused by the Jews, and the more recent Rhodesian and South African genocides, yet all foam at the mouth spewing their lies of 6 million jews being killed by the righteous Germans, which is nothing but a complete farse, a crock of bs. The holocaust is a ridiculously utter hoax and the only deaths of Jews in concentration camps (rightfully so due to their crimes against the society and the fact that they didn't belong there in the first place), were deaths caused of Typhus which would've NEVER happened had the Jews not instigated war across all of Europe, resulting in their confinement to camps which were plagued with Typhus as a result of war. No jew is a victim and Europeans are the largest genocide victims to date. From all ancient civilizations being flooded with non-Whites and utterly desecrated, to the modern anti-White propaganda which has plagued the world today at the hands of the Edomite Jews. We must not ignore their genocidal crimes against Adamkind any longer. They are offspring of serpents as Christ and John the Baptist both said.
