Zionism claims the right to a Jewish state in the land of Israel. The current Israeli state is embarking on a Zionist project of establishing a greater Israel. The Zionist claim to the Jewish right to statehood in the Jewish lands of Israel denies the indigenous Christians and Muslims rights to citizenship and self determination in their ancestral lands. Where two rights exist, power decides. Hence the current Palestinian genocide.

None of which would make it true that Jews aren't indigenous to the area. Or diminish their right to citizenship, independence, and self-determination.

It is exceedingly difficult to find a just and equitable outcome when there are two separate peoples who are indigenous to an area who both want to have self-determination and and independents and who don't beleive their self-determination will be effectuated if they are in the minority in a single state. This is a normal and common trait among peoples, whether they be religious or ethnic or nationalist communities. Hence the existence of so many efforts of smaller communities to seek independence, autonomy, or liberation from larger states - whether it be the Basque community in Spain, the Walloons in Belgium, the Quebecois in Canada, or what have you.

The solution that was applied successfully in India (but with traumatic impacts) was partition. The same proposal was contemplated in Palestine, but it was unable to be implemented.

Zionism is the belief that the Jewish people should have their own country, the same way the Japanese people or the Italian people or the Thai people or many other peoples of the world are allowed to have their own country. That belief can exist independently of the position of the current right-wing parties in Israel that such country's territory should include 100% of areas that were originally slated to be "Arab" under the 1948 partition plan. Partition would have been a way to effectuate both the Jewish people's and the Palestinian people's legitimate desires to have that level of self-determination, independence, and autonomy. Alas, it was not to be.
