Well, not quite; it's the ideology that Judaism should have a country, or maybe even Judaism as an ideology of particular émigrés who had the resources to leave and return should have a country.

It's highly distinguishable from the ethnicity in this specific case because Palestinians are pretty much genetically identical to Israelis, something that the Spanish blundered into discovering in the early days of genetic sequencing before having to retract the paper. Notably, this was not because anything was factually inaccurate, but because they caught all kinds of shit from the Israelis who insist that the "Arabs" are interlopers. The war essentially amounts to Jews who converted to Islam or Christianity being bombed to shit by Jews who didn't. If every Israeli converted to Islam tomorrow, or conversely if they decided that "Jews aren't proselytizers" belonged in the trash bin alongside "Jews aren't farmers" when the people on the other end were conversos, there'd be no war.

Instead all the people crowing "Amalek, Amelek" are simultaneously doing the red calf shit. It's a religious war where the worst heresy of Samaritanism is going after the second worst.
