Read Wikipedia on this charlatan. A Communist, anti-Zionist, and evidence he may have been an informer for military intelligence in Poland's postwar Communist regime. Interestingly, he was given a position in an Israeli university when he was stripped of his university chair by the anti-Semitic Polish regime of 1968. I suppose this vacuous and shrill diatribe is his way of showing his gratitude. Disgusting.
