I'm not sure what the Jan 4 Agreement was,
The Main Point here Being What The Arabs thought of Palestine in 1919.
It was a tiny part of the land Just liberated by the British From the Ottomans.
There were no "Palestinians' then.. just a few Arabs who might have to move a few miles and join other Arabs in the vast majority of the Liberated Territory which became all the Arab states.
How do you reconcile that statement regarding a 1919 document with the 1917 Balfour Declaration? Who where the people in the "existing non-Jewish communities in Palestine" if not Palestinians?
The Balfour Declaration
Dear Lord Rithchild,
I have much pleasure in conveying to you, on behalf of His Majesty's Government, the following declaration of sympathy with Jewish Zionist aspirations which has been submitted to, and approved by, the Cabinet.
His Majesty's Government view with favour the establishment in Palestine of a national home for the Jewish people, and will use their best endeavours to facilitate the achievement of this object, 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 should be grateful if you would bring this declaration to the knowledge of the Zionist Federation.
Signed: Arthur James Balfour
