Victor, as you have obviously never read anything about the San Remo conference and the Treat of Sevres,below is some info for you. "The High Contracting Parties agree to entrust, by application of the provisions of Article 22, the administration of Palestine, within such boundaries as may be determined by the Principal Allied Powers, to a Mandatory, to be selected by the said Powers. The Mandatory will be responsible for putting into effect the declaration originally made on November 8, 1917, by the British Government, and adopted by the other Allied Powers, in favour of the establishment in Palestine of a national home for the Jewish people, it being clearly understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country."
