He died today at 102. I met Prof. Ben Zion Netaniyahu at the University of Tel Aviv. He took part in several "encuentros" on the history of Spanish Jews, combatting the ideas of Americo Castro, who is even today the authority on the subject. Castro's thesis is that the "limpieza de sangre" exclusion and persecution of conversos was the mirror image of Jewish racism. I helped him to translate to Spanish things although he spoke Spanish. In person, like many of his generation, like Shimon Peres, he was obsessed by the Holocaust and in his mind, the Inquisition was Heydrich's Einsatzgruppen. I read some of his books and felt that his historic research was nothing less than a desperate almost kabbalistic way of trying to undo the Holocaust, to save Polish Jewry. That is the true origin of Bibi's behaviour, I recognize his father in everything he says.
