Also, not wishing to be rude but your post kind of implies yiu don’t know much about the background of all this, so here’s a potted history from the history books and primary sources (not just some dude with a TiK Tok / Instagram account).
Israel accepted the UNO partition plan in 1947.
The Arab League rejected it.
Israel legally came into existence in May 1948.
Sadly, Palestine did not (see above).
At that precise moment a 5-Arab Nation Army attacked the new Israel with the intention of destroying it.
The Arab armies spectacularly failed.
In that war, yes, Israel did take more land than they received in the partition plan, but they were fighting for survival (a defensive war turned into an offensive one - and interestingly in this civil war the Arab side used a great deal of sexual violence against Israelis as a weapon of war so they truly have form for it, meanwhile Israel did awful things too, like poisoning wells for example).
Jordan took the West Bank, Egypt the Gaza Strip. Palestine ceased to exist.
They could have set up a proto-Palestinian state in those areas, built, invested in infrastructure. But no, they preferred to do nothing for the Palestinians in the refugee camps, who sadly paid the price of the Arab failures.
Throughout the next 75 years, some Arab states recognised the State of Israel. But the PLO response was "No peace, No recognition, No negotiations" (they literally said that after they lost the six Day war and Israel said “Hey have your land back, just give us peace in return…please!”).
In 2000 at Camp David, Yasser Arafat walked out on the best deal he had ever been offered.
And here we are in 2023, and the Palestinians in Gaza are represented by a fascistic death cult that teach infant school children to hate Jews.
Also, if you really want to know about terrorising ordinary people (Israelis) on a daily basis, look up the first and second intifadas.
