In March, 1921, at the Cairo Conference, Winston Churchill decided to “buy off [Prince] Abdullah: to offer him a position in Transjordan.”
He proposed establishing a Jewish National Home in Palestine west of the Jordan River and a separate Arab entity in Palestine east of the Jordan River, and, Abdullah, if installed in authority in TransJordan إمارة شرق الأردن, would preside over the creation of such an Arab entity, disregarding objections that “since Transjordan had been included by the League of Nations in the territory of [mandated] Palestine, it was not open to Britain unilaterally to separate it from the rest of Palestine.”
In 1922, Winston Churchill, as Secretary of State for the Colonies, signed the British White Paper of June 1922, Churchill White Paper, severing 32,500 square miles from the Palestine Mandate, which encompassed 43,000 square miles.
Britain created TransJordan إمارة شرق الأردن from the severed Palestinian lterritory, and entitled them to the non-Palestinian rulers, the Hashemites.
The British Colonial Office regarded “the administrative separation of Transjordan as a merely provisional measure. It [was] decided not to allow Zionism in Transjordan for the present but also not to bar the door against it for all time.”
Sir Alec Kirkbride, British representative, cites: Transjordan was ". intended to serve as a reserve of land for use in the resettlement of Arabs once the National Home for the Jews in Palestine, which [Britain was] pledged to support, became an accomplished fact. There was no intention at that stage of forming the territory east of the River Jordan into an independent Arab state."
In 1923, lands eligible for Jewish settlement were reduced when the British transferred the Golan Heights רמת הגולן‎, which had belonged to the tribes of Dan שבט דן and Manasseh שבט מנשה from British Mandate control to Syria سورية‎, under French control.
In 1925, the British added 60,000 square kilometres of desert to eastern TransJordan إمارة شرق الأردن forming an arm connecting TransJordan إمارة شرق الأردن with Iraq العراق, and to cut Syria سورية off from Saudi Arabia المملكة العربية السعودية‎.
The British enacted restrictive regulations against the Jews, even when Arab leaders sought Jewish help in the development of TransJordan إمارة شرق الأردن.

On September 3, 1940,, at a luncheon with Chaim Weizmann, Prime Minister Winston Churchill approved the large-scale recruitment of Jewish forces in Palestine and the training of their officers.
A further 10,000 men, no more than 3,000 from Palestine, were to be recruited to Jewish units in the British Army for training in the United Kingdom.

On November 13, 1940, Christopher Eastwood sent the cable to Prime Minister Winston Churchill: I have accordingly decided, on the strong recommendation of Sir Harold MacMichael, that any Jewish arrivals must be refused admission to Palestine. PREM 4/51/1 page 91
On November 21, 1940, Christopher Eastwood sent the cable to Prime Minister Winston Churchill: The position is that the intention of the Government to remove Jewish refugees from Haifa to a British Colony has now been officially announced in Palestine. Its revocation would be interpreted only in one sense, as a surrender to Jewish agitation. If such an impression were created, not only would more and more shiploads be encouraged to descend upon us, but the political effect in the Middle East would be altogether deplorable.

Mordechai Gichon cites: “Churchill understood the Jews from an emotional standpoint. Addressing parliament on September 20, 1944, he declared that “a special unit of that race which has suffered indescribable torments from the Nazis should be represented as a distinct formation amongst the forces gathered for their final overthrow.”
