You’re just flat out lying at this point lol. 21-23% of the entire Israeli Jewish population is first-generation immigrants; 30-35% is second-generation, direct offspring of immigrants; 30-35% is third-generation; 10-15% is fourth-generation; under 5% is fifth generation or beyond. These are numbers are from the Israeli Central Bureau of Statistics. There’s also statistics that rather say 40-45% are third-generation with much less being fourth-generation or beyond, but with around the same amount or slightly less being first and second generation – I find the former estimates far more reasonable though. It’s estimated around 90-97% of Israeli Jews are descended from immigrants in the past century.

A majority of Israeli Jews are descended from immigrants of several Aliyah (immigration to “Zion” from outside of the lands of Palestine/Israel, practically starting from 1882 but mostly ramping up around the start of the British/Israeli oppression of Palestinians in the region in the early and mid 1900s). The most conservative estimates say that around 50-70% of Israel’s Jewish population growth since 1900 came from immigration, with most of the rest of the population growth coming from recent immigrants having children.

A significant portion of Israeli Jews came from immigration in the 90s, especially from the Soviet Union after its collapse – 1.4-1.6 million Jews (compared to Israel’s total current Jewish population of around 7.4 million) immigrated to Israel following the collapse of the USSR. Over a fifth of the entire Israeli Jewish population in just the span of one generation.

It’s crazy for you to try to state that modern Israelis aren’t primarily (nearly exclusively) descended from relatively recent immigrants.
