Between 1917 and 1947, thousands of Jews throughout the world left their homes and moved to Palestine because they heard that a future national home for the Jewish people was being established there. The "Mandate for Palestine," an historic League of Nations document, laid down the Jewish legal right to settle anywhere in western Palestine, between the Jordan River and the Mediterranean Sea, an entitlement unaltered in international law. Fifty-one member countries - the entire League of Nations - unanimously declared on July 24, 1922: "Whereas recognition has been given to the historical connection of the Jewish people with Palestine and to the grounds for reconstituting their national home in that country."
It is important to note that political rights to self-determination as a polity for Arabs were guaranteed by the same League of Nations in four other mandates - in Lebanon and Syria (the French Mandate), Iraq, and later Trans-Jordan [the British Mandate].
Any attempt to negate the Jewish people's right to Palestine - the Land of Israel - and to deny them access and control in the area designated for the Jewish people by the League of Nations, is a serious infringement of international law.
