It was never Palestinian. They never identified as such, this nationality didn't exist 100 years ago. They all identification themselves as Jordanians and Egyptians, even their flag was copied from Jordan.
You can't give me a name of even a single Palestinian man that identified himself as Palestinian. Not even one Palestinian poet. Not a Palestinian currency (Don't send me British mandate coins that havs Eretz Israel written on them). The word Palestine is based on the ethnically Greek Philistines which have absolutely nothing to do with the Palestinians. Arabs don't even have the sound P in their language to say Palestine.
Arabs arrived here in the 600s after they did exactly what they accuse us of. They continued to do so ever since. Tried to do the same in the 1900s before Israel's establishment as a state and in 1948 when it was established, in the 1960s they planned a war and in 1967 Egypt started a naval blockade against Israel and Israel told them its an act of war and absolutely wrecked Egypt,but it didn't attack Jordan and Syria, and even asked them to not enter the war. Then the Syrians and Jordanians decided to attack us, before that Jordan told what you call today the Palestinians, that they need to leave their houses and return in a day after Israel is destroyed. Then Israel beat the shit out of them as well.
Winners keep it all, Arabs lost because it's all they're capable of doing against us.
Then they tried to do the same in 1973 and don't kid yourself that they would have stopped at the Sinai and Golan, if they were even capable of getting them. Then they lost again.
Israel tried to deal with the Palestinians, deals that would give them 95 percent of the West Bank, gave away Gaza, Trump's deal which offered so much to the Palestinians just in 2020 etc. All were rejected.
The two state solution was offered many times, seems like the only solution is the "**** all the Palestinians, we had enough" solution.
