No! Israel is Israel. There are no such people or a country called Palestine. It was an area called that by the Romans and there were no so-called Palestinians until 1948.
You are absolutely correct!
Genesis 12:3
Palestinians are actually Arabs that lived in an area called Palestine....The history of the Israeli–Palestinian conflict began with the establishment of the state of Israel in 1948. This conflict came from the violence in the Palestine area between Israelis and Arabs from 1920 and erupted into full-scale hostilities in the 1947–48 civil war.
