"What interested me in Blum as a Jew was precisely that: the hatred he aroused. We find it hard today even to imagine the degree of overt, unapologetic prejudice and dislike that someone like Blum could inspire in those years, primarily and simply on account of his Jewish origin. On the other hand Blum himself was often deaf to the scale and implications of public anti-Semitism and its invocation against him. There was, of course, a certain ambivalence in Blum’s own identity: unashamedly and totally French, he was no less overtly and proudly Jewish. In later years he combined great sympathy for the newborn Jewish state in the Middle East with near indifference to the Zionist message itself. These ostensibly incompatible identifications and enthusiasms were perhaps not so far from my own at various times, which may explain my long-standing interest in the man."
