The largest demographic group in Israel, the Mizrahi, look indistinguishable from other Middle-Eastern people. You couldn't tell them apart from Palestinians or any other Arabs. Bringing American notions of race into this is a very foolish endeavor.
While the Israeli government does not track ethnicity of its Jewish population, many studies have been completed.
Ashkenazi Jews were historically the majority of Jews in Israel. However as immigration from European countries and the USSR increased, the demographics changed. The majority of French Jews are Sephardic and many Jews from the USSR are Mizrahi.
Of the 7 million Jewish Israelis, only 900,000 immigrated from the Arab world.
So a completely false narrative peddled by someone who clearly has an agenda.
