"I see no elephant in my basement;
an elephant could not be concealed from sight in my basement;
therefore, there is no elephant in my basement."
There was no information of mass exterminations at Auschwitz during the relevant period,
Between May 1942 and June 1944, almost none of the messages reaching the west had referred to Auschwitz as the destination of Jewish deportees, or as a killing centre. Nor had the name of Auschwitz made any impression on those who were building up what they believed to be an increasingly comprehensive picture of the fate of the Jews.
and mass exterminations at Auschwitz could not have been kept secret.
Laqueur explains that mass exterminations at Auschwitz could not have been concealed, noting that Auschwitz was "a veritable archipelago," that "Auschwitz inmates ... were, in fact, dispersed all over Silesia, and ... met with thousands of people," that "hundreds of civilian employees ... worked at Auschwitz," and that "journalists travelled in the General Government and were bound to hear," etc.
Therefore, there were no mass exterminations at Auschwitz.
An inescapable conclusion!
