They are predominantly so. Ashkenazi Jews are from Eastern Europe. Sephardic Jews are from Spain. Zionism as a movement was started in Europe by Europeans. Israel is a European colony state.
Don't fool yourself, you are repeating antisemitic slurs. The Jews in Israel never left, and Zionisim is something like 2,000 years old (it's as old the Babylonian exile). Israel is as far from "colony state" as you can get - it's literally the opposite, it's an example of the native people getting their own land back.
