This is not even remotely true. In fact, ethnically, it has been demonstrated that the Palestinians present today are in fact the true descendants of the original inhabitants of the area, including the original Israelites from that region, and are not, in fact, migrants that arrived later or were Arabs from outside (though such people also exist but do not make up the majority). [1] [2]

What is undisputed is that those called Israeli today are majority NOT traditionally Middle Eastern, whose ethnic origins trace back only to Europe, Russia, and pretty much anywhere except the Middle East, with the only exceptions being, that's right, Arab Jews (a concept Zionists struggle with) that have lived in Palestine for centuries. The whole concept of Aliyah is about immigrating to Palestine. What their true origins are is difficult to pinpoint widely because commercial genetic testing to find out their actual ethnic origins is banned in Israel or so highly regulated it is effectively blocked.

Zionism is a European settler colonial concept. It harmed primarily Arabs, Muslim, Christian, and Jew, and remain one of the last an anachronistic relics of the imperial settler colonies of the past 500 years.
