Are you arguing just to argue? In 1947 the UN decided on borders for an Arab state - they did not name that state and at the time the term Palestine was not the name of any supposed rulers of that Arab state.

The point under discussion above is the fact that the Arabs rejected the borders of this proposed Arab state. So they started a war and the borders were changed. That's the risk they took and lost. It is disingenuous to claim that Israelis stole Arab land at this point - the Arabs tried to steal land and lost.
