The intent of the letter was for a Jewish State and homeland. It was lobbied hard by the Zionists, and by the Brits for selfish understandable reasons. The Brits knew that this was not going to go well for the Palestinians, I believe, at least from where I am in my "study" at this point.
The declaration was adopted by the newly created league of nations in 1922, and Belfour and was well alive.
There is just so much to absorb and study here, but one thing is clear that the agreement was the fuse that lead to Israel becoming a State in 1948, and the laws that came along that journey.
The declaration was written with the intent that Israel was the homeland for the Jews
Churchill in 1921, after the War, responding to Mousa Kazim el Husseini rejecting the declaration....
Our position in this country is based upon the events of the war, ratified, as they have been, by the treaties signed by the victorious Powers. I thought, when listening to your statements, that it seemed that the Arabs of Palestine had overthrown the Turkish Government. That is the reverse of the true facts. It has been the armies of Britain which have liberated these regions.
It was basically a "lump it " remark it seems. Churchill was basically saying to the former mayor of Jerusalem....'you did not win the war, we did, and "Israel" is the rightful homeland of the Jews, whether you like it or not."
From what I understand so far, and I am certainly open to change my views, any talk about the native Arab population having rights, at least to political power and things like owing properties is talk.
In part the 1920 San Remo declaration reads; doubling down on the Balfour agreement....
The Mandatory will be responsible for putting into effect the declaration originally made on November 8, 1917, by the British Government, and adopted by the other Allied Powers, in favour of the establishment in Palestine of a national home for the Jewish people, it being clearly understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country.
I believe history is clear that the civil rights of the native Palestinians were violated. to what degree their religious rights were violated is less clear to me. Again this complex and the more one studies this the more complex it seems to be.
