Palestine didn't exist as a state and never did until the same time as Israel. That land was part of the Ottoman empire, and then the British mandate. before that it was controlled by various empires throughout history. Both the Palestinians and Israelis are indigenous to that land, and if Palestine and other Arab nations hadn't tried to wipe out the Jews in 1948 the moment Israel was established, maybe Israel wouldn't be trying to take what's left of Palestine.

Well so long as Hamas is getting rockets, Israel needs them too. When you figure out how to stop rockets getting to Hamas, then we can talk about disarming Israel.
