I also felt like taking Israel back after such a long time and driving out the inhabitants is difficult to defend.

Yikes. It's not just "difficult to defend", it's indefensible. Israel was founded by the brutal expulsion of hundreds of thousands of people from their homes. That alone is enough to make the foundation of the modern state of Israel an act of evil and a crime against humanity. The erasure of Palestinian history, though, is also disgusting. Palestinians are not Arabs. Just like the Romans didn't displace the people of Britain in the classical period and the Normans didn't displace them in the mediaeval, the arab conquest of Palestine didn't displace the previous inhabitants. Modern Palestinians are largely descended from ancient Palestinians (and therefore Jews) who converted during/after the conquest.

Now that absolutely does not matter. The fact is that Palestinians were living in the region and had a right to their homes that was breached during the creation of Israel - whether their ancestors had been there for 200 or 2000 years doesn't matter. They were the legitimate inhabitants and were unlawfully ejected, that's what matters. But painting them as a separate population who somehow "replaced" the "real" inhabitants is not cool. The idea that anyone but Israel are at fault when the entire nation was founded in an enormous act of ethnic cleansing is just revolting. Even if Arabs had in fact "ejected" the original inhabitants during the conquest it still wouldn't be acceptable to eject their inhabitants from their homeland of the last ~1400 years, but that isn't even true and modern Palestinians literally are the descendants of ancient /classical era Jews.

Israel wasn't "taken back". It wasn't "recreated". Zionists have no connection to the land they have stolen and the modern state of Israel has absolutely no continuity with any ancient states. In fact the only people who can meaningfully claim to be the inheritors of the ancient state of Israel are the Palestinians who were ejected by a bunch of white people with German, other central European, and american accents in the late 1940s. Just the idea of "enforcing" a contract which literally just said "you give us all the best land in your country, and in return we get all the best land in your country" (the partition plan, which Britain had absolutely no moral right to force on anyone in the first place) is mask off, unapologetic, Hitlerian Nazi rhetoric, and it's not more acceptable just because the beneficiaries are Jewish.

God Denazification was a pathetic failure. Just look at you talking about how Palestinians are partially responsible for the genocide and ethnic cleansing being visited upon them... Because they didn't agree to be ethnically cleansed "peacefully". Just truly, honestly sickening and evil.
