"Publicly Great Britain reaffirmed commitment to the principle of self-determination of the Arabs. In November 1918, France and Great Britain signed the Anglo-French Declaration, which affirmed that their goal [... was] the complete and final liberation of the peoples who have for so long been oppressed by the Turks, and the setting up of national governments and administrations deriving their authority from the free exercise of the initiative and choice of the indigenous populations.ix In 1919, the Allied powers met in Paris to determine the status of the non-self-governing territory that had been part of the former Ottoman Empire. Member states of the League of Nations decided to establish a temporary Mandate System in accordance with the Covenant of the League of Nations to facilitate the independence of these territories.x The August 1920 Treaty of Sèvres between the Allied Powers and Turkey affirmed that Palestine be provisionally recognised as an independent State subject to the rendering of administrative advice and assistance by a Mandatory until such time as they are able to stand alone.xi<quoted text>
The Mandate clearly ignores the local populations political rights.
Do you really want to play this game again when you have refused to give a legal basis for the Palestinians national claim to the land?
It clearly opened up settlement in W.Palestine for Jewish immigration to create a state.
Why do you hold different laws for each Mandate?
In 1920, the League of Nations entrusted the temporary administration (Mandate) of Palestine to Great Britain, as a Class A Mandate a categorization closest to independence.xiiThe Mandate for Palestine, however, aimed to facilitate the colonization of the country through Jewish immigration and settlement in order to secure the establishment of the Jewish national home, in line with the political commitment set out in the Balfour Declaration. The Mandate accorded the Jewish minority in the country and non-resident Jews residing elsewhere full political rights; it granted the Palestinian Arab majority only civil and religious rights.
[I]n the case of the independent nation of Palestine, observed the British Secretary of Foreign Affairs privately,we do not propose even to go through the form of consulting the wishes of the present inhabitants of the country(as was required by the League of Nations).Zionism, be it right or wrong, good or bad, is rooted in age-long traditions, in present needs, in future hopes, of far profounder import than the desires and prejudices of the 700,000 Arabs who now inhabit that ancient land.xiii The British Mandate of Palestine was thus based on an inherent contradiction: the simultaneous establishment of an independent state of Palestine for all its citizens on the territory of Mandate Palestine, and a Jewish national home within or on that same territory."
If you can't see the writing on the wall then there is nothing else I can say.
