I suggest you read up on history. At the turn of the last century the region was part of the Ottoman Turkish Empire. Jews had been legally buying land for Jewish settlement and development of a Zionist state. The land was the Jewish ancestral homeland, a land where many Jewish kings had ruled. There were Arabs of different tribes and clans in the area but there was no Palestinian people, no Palestinian kingdom, and there had never been one. The Arabs there did not call themselves Palestinians.
During WWI, England issued the Balfour Declaration recognizing Jewish aspirations for a state of their own in the region, subject to fair treatment of then existing non-jewish residents. England also made promises to Arab leaders for their help in the war. Jordan, Iraq, and Saudo Arabia were created as nation- states or British colonies to partly fulfill such promises. But England made no promises to “Palestinians” as they did not exist as a national entity. Neither did it take Palestinian lands and give them to the Jews for settlement. Rather the Jewish agencies purchased them legally from Arab landowners or from the colonial government. The land purchased was largely desert. The Jews founded agricultural communities and developed the land. The increase in food production and related industries spawned significant Arab migration into what was then the British mandate of Palestine. That’s right: many of the current Palestinians descended from people who immigrated to Palestine in the first part of the last century.
The Palestinians did not even think of themselves as a nationality till the 1960s, twenty years after the state of Israel had been established. The PLO was founded in 1964. It’s first chairman, Yassir Arafat, was born in Egypt.
So you may want to start anew but only after retracting the ahistorical falsehood of “ England taking Palestinian lands for Jewish settlement” That never happened.
