though it should be noted that Jordan, the eastern 78% percent of the Palestine Mandate - all of which was to have been the Jewish homeland according to the League of Nations...The British Mandate of Palestine was one where Transjordan and Palestine were always treated as two separate entities under the one mandate, so any claims that any percentage of what was to be a Jewish homeland (as far as I know, the League of Nations didn't say at any point that the entire Mandate was to be the Jewish homeland) was given away is imo very misleading...
Here's some information on the Mandate for anyone interested. Note, the bolding is mine so to stress the point that Transjordan and Palestine were two distinct territories within the one mandate:
"All the mandates over Arab countries, including Palestine, were treated as class 'A' Mandates, applicable to territories whose independence had been provisionally recognized in the Covenant of the League of Nations. The various mandate instruments were drafted by the Mandatory Powers concerned but subject to the approval of the League of Nations.
The mandate for Iraq, while in the process of being drafted, was amended to provide for the signature of a treaty between Britain and Iraq, which was concluded in 1922. This was supplemented by further agreements, all approved by the League as meeting with the requirements of article 22 of the Covenant. Iraq obtained formal independence on 3 October 1932.
The Mandate for Syria and Lebanon did not provide for any special treatment as in the case of Iraq. Both territories were governed under the full control of France until the Mandate was terminated. Lebanon achieved full independence on 22 November 1943 and Syria on 1 January 1944.
Palestine and Transjordan (as it was then called) were included in the same Mandate but treated as distinct territories. Article 25 of the Palestine Mandate empowered Great Britain to withhold, with the League's approval, the implementation of any provision of the Mandate in Transjordan. On the request of the British Government the Council of the League, on 16 September 1922, passed a resolution effectively approving a separate administration for Transjordan. This separate administration continued until the territory attained independence as the Kingdom of Jordan on 22 March 1946.
Only in the case of Palestine did the Mandate, with its inherent contradictions, lead not to the independence provisionally recognized in the Covenant, but towards conflict that was to continue six decades later."
