Just have to say one thing the Palestinian people declared their state in 1988, until then there was no Palestinian state or people. You admitted this on another thread.
The Treaty of Peace between the allied powers and Turkey officially ending World War I was signed in Lausanne, Switzerland, on 24 July 1923.121 Setting out the legal status of the territories detached from Turkey, the Treaty had the effect of law in Palestine, as it was extended to this country by an ordinance,122 on 6 August 1924.
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
Drawing up the framework of nationality, Article 30 of the Treaty of Lausanne stated:
“Turkish subjects habitually resident in territory which in accordance with the provisions of the present Treaty is detached from Turkey will become ipso facto, in the conditions laid down by the local law, nationals of the State to which such territory is transferred.”
