When did the state of Palestine come into existence according to International law ? Or are you unable to answer this question truthfully ?The status of Palestine and the nationality of its inhabitants were finally settled by the Treaty of Lausanne from the perspective of public international law. In a report submitted to the League of Nations, the British government pointed out: “The ratification of the Treaty of Lausanne in Aug., 1924, finally regularised the international status of Palestine.”123 And, thereafter, “Palestine could, at last, obtain a separate nationality.”124
Henceforth, Palestinian nationality was first founded, according to international law, on 6 August 1924. And “treaty nationality in Palestine runs from that date.”139 The Treaty of Lausanne had transformed the de facto status of Palestinian nationality into de jure existence from the angle of international law.140 Meanwhile, the Ottoman Empire ceased to exist.141 Likewise, on 6 August 1924, for the first time ever, international law certified the birth of the ‘Palestinian people’ as distinct from all other peoples.
