I wouldn’t characterize him as a “ghetto Jew”. Jews of the old ghettos lived by their prayers and their wits. As for the former, he says none. As for the latter, he has none. An analogy with the Judenrat would be more accurate, but I won’t make that analogy. The Judenrat were given an impossibly conflicted job, caring for their community and preserving themselves by selling their community out, and they gave the job to those who only cared about their selves, so they would do it as the Germans wanted. He is only concerned with aggrandizing himself, and fools himself into believing that he actually cares about humanity and his people. He’s out of touch with reality, and thanking a bus driver as if he had personally done Peres a favor by not getting incinerated is just the latest sign of it.
I will defer to your greater expertise in trying to find the exactly accurate taxonomy for Peres.
My effort at classifying him was meant to reflect his constant policies of “national suicide” (giving away more and more land...including areas that are, or were, plainly necessary for effective defense), and of course his disasterous sell-out at Oslo.
