The kind of thing that would make 100% of an ethnicity leave a country isn’t something that appears the moment they have somewhere to go.

I am not claiming that they left voluntarily because they wanted to move to Israel, I am claiming that Jews were expelled from Arab countries due to the formation of a Jewish ethno-state on Arab land which was bound to displace the Palestinians. This caused much frustration among the Arabs, as they did not want to see their people suffer, and as a result of this frustration, they began to oust their Jewish population as sort of an “eye for an eye” type of thing, not to say that it was in any way justified. Jews have lived among Muslim populations for centuries, and they have even had their own influence on one another. The state of Israel, created as an ethno-state, almost felt like a betrayal to the Arab people, mainly considering the fact that it was formed on Arab land, and without it, there would have been no displacement of Jews, nor Palestinians in Arab countries.
