British did not give same land to two people.

A Jewish state west of the Jordan was part of the deal for helping to get rid of the Ottomans. The Arabs got Transjordan as part of the same deal. Nobody would have been forced to move. Arabs who did not move but stayed in Israel have a better life than Arabs anywhere else in the Middle East, with democratic rights limited only because of their potential as a security threat, so we are not talking about some evil, oppressive alien regime. Whether there ever would be enough Jews to constitute a Jewish state was in doubt until the rise of the Nazis.


The Balfour Declaration was only part of the picture. The British did not give away the same land to two different people.
