Unfortunately, this is only a partial answer. Antisemitic violence in the region predates Israel's establishment by decades, and would still exist even if Israel did not. Assuming that fundamentalist Palestinian militancy is merely/solely a result of their territorial losses on the battlefield in the past, and/or only a function of Israeli policy since the 1960s, is historically disingenuous to the extreme. It severely detracts from the agency of Palestinian fundamentalist militants, reducing them to a one-dimensional, reactionary force, and ignores the much greater complexity and maximalist aims of their driving ideology.
