Omer Bartov, the distinguished military historian, came from a family that had lived in Buczacz but emigrated to Israel. He begins by explaining that the Jews did not live segregated from the Christian population; the entire notion of a shtetl existing in some sort of splendid (or sordid) isolation is merely a figment of Jewish literary and folkloristic imagination. Integration was what made the existence of such towns possible. It was also what made the genocide there, when it occurred, a communal event, both cruel and intimate, filled with gratuitous violence and betrayal as well as flashes of altruism and kindness.
