The palestinians never owned the land in the first place, it belonged to the British and before the British owned it no one at all owned it so the Jews can be there if they want to be!
The Jews had no land left after the holocaust and they needed to have their own land sometime so they got their own country to keep them safe and god was the one who gave it to them.
I say that the Israelis deserved the land because they defended the war to get the land and the bible does say that god gave them the land so it is only fair if they did get the land.
