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 (which would include Jews who lived there since before Aliyah). 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 since 1900.

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). Even 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. And those are really conservative estimates, the actual amount is likely much higher than that.

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. Yet second- and third-generation Israeli Jews make up like 3-3.5x as much still.

It’s crazy for you to try to state that modern Israelis aren’t primarily (nearly exclusively) descended from relatively recent immigrants who displaced (and outright genocided) the native population. You straight up just made that up without consulting any history/statistics, not even Israel’s own statistics lol. Palestine faced a colonization and replacement by Jewish immigrants – according to the Jewish Virtual Library, 8% of people in the region were Jewish in 1882; then 11-13% after the end of WW1, after the adoption of a Zionist policy for Palestine and occupation by the UK (see the Balfour Declaration); then 32% in 1947 after several Aliyah; then in 1948 – the year the Israel was formally established and immigrants were shipped in from all over the globe, and the year European immigrants to Israel started all-out total war and genocide against Palestinians – that number jumped to 82%. It is not Jews’ “indigenous land”, 93%+ of people in the region were Arab Muslims at the time of the first Aliyah, hundreds of thousands compared to the 9,000 Jews and even less Christians. Jews hadn’t been the majority in the region since the 4th century, Arabs & Muslims have been the majority since before the Magna Carta, the Crusades, European Feudalism, they were most of the population when France just started to exist.

Considering the actual facts of the situation, your justification basically becomes “colonization and apartheid in the modern day is okay because some other people they identified with lived there 1,500-3,000 years ago”, in which case I have some bad news for like, 95% of Europeans, Middle Easterners, and Asians, who all exist on lands which were someone elses in that same time period. Ethnonationalism with feeling you have a “right” to certain land you have no actual connection to based on some ancient “predecessor” civilization that had those lands stolen from them before Hindu-Arabic numerals existed is a strong hint that you’re in the wrong (see: Nazism). Modern Jews are about as indigenous to Israel as the modern Japanese are to Korea, or modern Turkish are to Mongolia.

Zionism is modern-day ethnonationalism and colonialism by predominantly non-Levantine peoples (more than half of those being primarily European in ancestry). Its purpose is creating and justifying an ethnostate where Jews are superior and have rights that other groups don’t have – and such things are cemented in the Israeli constitution and law. To exist, Israel requires relegating non-Jews to second-class personhood and requires (or required at some recent point in time) commiting acts of genocide towards certain non-Jews; abolishing that would be abolishing the concept of Israel and Zionism as a whole. There is no real moral defense of the state of Israel.
