Actually, technically, officially
“Israel” (declared may 1948) existed before “Palestine” (declared 1988).
The Jews and the Arabs have both been there for millennia, and the land has been contested since the dawn of recorded history.
It was originally called Canaan in the late Bronze Age (1500 - 1200 BCE).
Then in the Iron Age it was called Judea.
Then the Romans conquered the land and called it Syria Palestina (the land of Syrian “Phillistines”, aka uncultured/uncivilized people.)
Later that evolved into Palestine, which wasn’t codified until 1988, 40 years after the formation of Israel.
Both peoples have been there for millennia, both peoples have been committing atrocities on one another, and both peoples have a legitimate claim to the land.
This isn’t a simple black and white issue with good guys and bad guys. Claiming Israel is the bad guys because they’re the current aggressors, is like walking in on a fight and accusing the one who’s currently winning of being the whole reason for the fight in the first place.
You have to know the whole story, unbiased, looking from both sides, to understand a current conflict.
These lands and these people’s need outside arbitration.
They’re incapable of coming to a peaceful solution on their own. They’re too proud and they both feel too entitled and righteous.
One of them is currently more monied and has more support from imperialist governments, but they’ve both done horrible things to one another and ended millions of eachothers lives over millennia.
Israel is trying to put an end to it forever in the most effective way they can think of.
Violence.
It’s not fair.
If you study history, you will see not much about us is fair.
In recent times we have become abnormally civilized, but only just barely.
I’m aware of all of that.
The Arab-Israeli civil war of 1948 (Arabs call it the Nakba) actually started because of the first rejection by the Arabs of a peaceful two state partition.
In the Palestinian mind, right from the start of the Balfour Declaration in 1917, the British and the European Jews were seen as an invading force, and the formation of Israel was seen as the entrenchment of that invading force.
Prior to the Balfour Declaration and British backed migration of the European Jews, the Arabs outnumbered the Jews 10 to 1 in that region, and it was unofficially considered to be their lands. They saw the mass migration as an invasion and a threat to their sovereignty and culture, as peoples generally do.
Today only 44% of people living within the territory of Palestine are Arabs, and 52% are Jews.
Based on these numbers it would seem they were right to be afraid.
