Israelis started it, read some history. Palestinians are defending themselves from an ongoing ethnic cleansing and occupation that began before 1948.

You seem to wrongly assume that just because the invaders are Jewish that they are somewhat indigenous and somehow that justifies them committing a genocide. Never mind that nothing justifies a genocide not even if Israel’s narrative was true. After all the Geneva Convention exists for a reason. The entire narrative is also false.

This is what two Jewish sources one historical and one modern had to say about the Muslim Conquest of the Levant:

In 638 CE the Byzantine Empire lost control of the Levant. The Arab Islamic Empire under Caliph Omar conquered Jerusalem and the lands of Mesopotamia, Syria, Palestine and Egypt. As a political system, Islam created radically new conditions for Jewish economic, social, and intellectual development.[132] Caliph Omar permitted the Jews to reestablish their presence in Jerusalem–after a lapse of 500 years.[133] Jewish tradition regards Caliph Omar as a benevolent ruler and the Midrash (Nistarot de-Rav Shimon bar Yoḥai) refers to him as a “friend of Israel”.[133]

And next is a quote from Ben-Gurion himself:

“The fellahin are not descendants of the Arab conquerors, who captured Eretz Israel and Syria in the seventh century CE. The Arab victors did not destroy the agricultural population they found in the country. They expelled only the alien Byzantine rulers, and did not touch the local population. Nor did the Arabs go in for settlement. Even in their former habitations the Arabs did not engage in farming…their whole interest in the new countries was political, religious and material: to rule, to propagate Islam, and to collect taxes…the Jewish farmer, like any other farmer, was not easily torn from his soil…Despite the repression and suffering the rural population remained unchanged.” [7]

An interesting post about the indigeneity of Palestinians reviewing a book by Israeli historian Shlomo Sand https://blogs.umb.edu/joinercenter/2012/10/09/review-of-shlomo-sand-the-invention-of-the-jewish-people-london-verso-2009-translated-by-yael-lotan/

The Zionist settlers aren’t innocent victims here, they knew well beforehand what kind of response they will elicit from the locals:

[It is the] iron law of every colonizing movement, a law which knows of no exceptions, a law which existed in all times and under all circumstances. If you wish to colonize a land in which people are already living, you must provide a garrison on your behalf. Or else – or else, give up your colonization, for without an armed force which will render physically impossible any attempts to destroy or prevent this colonization, colonization is impossible, not “difficult”, not “dangerous” but IMPOSSIBLE! … Zionism is a colonizing adventure and therefore it stands or falls by the question of armed force. It is important to build, it is important to speak Hebrew, but, unfortunately, it is even more important to be able to shoot – or else I am through with playing at colonialization.

– As quoted by Lenni Brenner, in The Iron Wall: Zionist Revisionism from Jabotinsky to Shamir (1984), where the quotation is cited as being from “The Iron Law” copied from https://en.wikiquote.org/wiki/Ze’ev_Jabotinsky

The Iron Wall Essay here: https://en.jabotinsky.org/media/9747/the-iron-wall.pdf by the same Zionist monster quoted above makes it clear that at least since 1923, Zionist settlers did not want peace and only wanted to dominate Palestinians through force.
