You mean when King David granted lands to the tribes?
Or more recently when the British mandate was lifted, and Jordan and Israel were granted nation status by the UN? Do you know how India and Pakistan was founded?
We're not talking about India or Pakistan ... We are talking about how European Jews (primarily) did what they did when given power by the Brits. They went town to town commiting atrocities and massacres.
Palestinian land wasn't anyone's to take and or give away to. Arabs fought in WW1 along side British and were promised that the land of Palestine would be given back to them. They broke that promise and gave the land to European Jews. ....
When they gave the land to them ; there was only 10% Jewish people in Palestine. Since 1975 state of Israel has stolen most of Palestinian land.
There You go; there's the true history which Israel doesn't teach their people. Israel brainwashes their people.
