The Nazis tried their best to hide the crimes of their Third Reich from the world, because even they knew that many of their people and the world at large would be appalled.

It amazes me that Israel’s leadership has no such concerns apparently. Thus is the strength of belief in their control of the narrative.

There is nothing new about denial of the crime of genocide or silence about genocide. From the beginning of the war, mainly for political reasons, Nazi Germany did everything they could to keep international public opinion, and above all the Allied and neutral countries, but also the potential victims, in the dark about the extermination of people in the occupied countries.

Among themselves, however, the narrow circle of the Nazi ruling elite did not conceal these criminal acts.

Addressing high ranking officers in Poznań on October 4, 1943, Himmler, the head of the German police and the SS, said that “Most of you here know what it means when 100 corpses lie next to each other, when 500 lie there. . … This is an honor roll in our history which has never been and never will be put in writing” (IMT translation).
