Judaism and Islam are equally anti-Christian. One is an explicit rejection of Jesus Christ as both Messiah and God, the other is a kind of Christian heresy which also rejects Jesus Christ as God.
Israel is formally by law a Jewish state, where national rights in Israel belong only to Jewish people and the right to exercise self-determination in Israel is unique to the Jewish people. It is founded in its essence by taking a place with a majority Arab population and changing it to one with a majority Jewish population where they and only they have a right to self-determination. The only way this can be done is through a kind of colonization, and obvious (both in hindsight and in history) transfer of the local population.
The idea of "transfer" of the local Arabs is not new, didn't start with the October attacks, and isn't because of some kind of moral culpability of Palestinian Arabs for terrorism. It is baked into Zionism from the beginning - from the 1890s. The idea is that the right of Jews to have a homeland in supersedes the rights of the Arabs who already lived there. This view was expressed by all of the major leaders of early Zionism - Theodor Herzl, David Ben-Gurion, Berl Katznelson, Moshe Sharett, Chaim Wiezmann, etc. Like Bonfire04 here, they pointed to (forced) population movements in the collapse of the Ottoman empire as justification. They said it was a pragmatic and humane solution - with the alternative to the "humane" solution being the inhumane one. The main challenge of Zionism was to solve this "Arab question". The formula of solving the "Arab question" comes from the 1920s - with some irony predating the "Jewish question" of the Nazi holocaust by a decade. One great quote from 1940 from Ze'ev Jabotinsky was "the world has become accustomed to the idea of mass migrations and has become fond of them. … Hitler - as odious as he is to us - has given this idea a good name in the world." (a recent article published in Haaretz
here if you care to read).
This kind of ethnic tribalism is fundamentally anti-Christian.
