There was never a Palestinian state or country, or a Palestinian (Philistine) president, or a Palestinian army with a Palestinian government to govern over Palestinian borders. There was never a Palestinian Olympic team, or a soccer team, or any Palestinian sports team. Palestina is just a nickname given by a roman governor named Hadrian, to the region of Judea and Samaria, after Jews revolted against Romans. So that land was always known as Judea, Samaria , Galilee, etc.
By the way,….every Arabic country pronounces Palestine in their own Arabic language as Philistiia. The Tanakh explains how Israel defeated the Philistines when King David killed the giant Philistine named Goliath. So…only God can decide to whom that land belongs, and so far God designated the land as a place of habitation for Israelis.
The radical Islamists are only interested to kill Jews (as shown by the Oct 7 attack of children and women) , regardless of how much freedom Palestinians get in Gaza. So, it’s not about the land of Palestine, but only about the extermination of Jews.
