"The story [that Eichmann was born in Palestine and spoke Hebrew] is a common thread winding through the public's perception of Eichmann ... in 1944 Eichmann used it offensively in Hungary to underpin his authority. Wisliceny used it to make the Jewish community afraid of his commander, who knew everything, could read everything, and - a masterstroke of caricature - looked so Jewish himself that he could move undetected among the Jews at any time. This terrifying scenario made such a lasting impression that after the war, people were frightened Eichmann might secretly have gone to Palestine, posing as a Jew, and could be hiding there among the survivors."
