Let's just stick with source documentation from official archives, no partisan sites no propaganda sites. The UN archives, for example, which demonstrate that as early as 1920, the British knew that the Jews intended to dispossess the indigenous people of Palestine.

This memorandum constitutes His Majesty's Government's account of their administration of the league of Nations mandate in Palestine, and is sent to you in accordance with the undertaking given in my note of 2nd April, in which I had the honour to request that the problem of Palestine should be placed on the Agenda of the General Assembly at its next regular session.
