The League of Nations, which the #USA based United Nations replaced, made clear;

Article 22 of The League of Nations Covenant stated that the right of “those colonies and territories which, as a consequence of the late war, have ceased to be under the sovereignty of the States which formerly governed them and which are inhabited by peoples not yet able to stand by themselves…there should be applied the principle that the well being and development of such people form a sacred trust of civilisation and that the securities for the performance of this trust should be embodied in this Covenant”.

Also the British Government in a White Paper, May 17 1939, concluded;

1. “The proposal of partition recommended by the Royal Commission, namely the establishment of self-supporting independent Arab and Jewish states within Palestine, has been found to be impracticable.
2. His Majesty’s Government now declares unequivocally that it is not part of their policy that Palestine should become a Jewish state.
   
3. The object of His Majesty’s Government is the establishment within 10 years  (i.e., by the end of its Mandate) of an independent Palestine State…in which Arabs and Jews share in government in such a way as to ensure that the essential interests of each community are safeguarded”.

But the Zionists managed to threaten and bribe politicians and using the Balfour Declaration as prove of their right of a Jewish State.  And so started the Palestinian’s Nakba, their ‘holocaust’!
