In the 19th century, European Christians often reported on the pogroms waged by Arabs on local Jews - in Safed, 1860's, for example. The forefathers of the Palestinians were happy to rub in Jews' dhimmi status. Then there was the 1929 massacre in Hebron; the expulsion of Jews from east Jerusalem in the 1920's. (Further afield, massacres of Jews occurred periodically in Damascus, Fez,...) The Palestinians were never innocent bystanders. And after 1948, they still had the West Bank and Gaza, but didn't push for a state. Arab obsession for destroying Israel has always fare exceeded desire for a Palestinian state. The Nakba observation is simply another facet of this obsession, and a means of deligitimization.
