I am Palestinian and all my ancestors were born in Palestine. My grandpa was forced to leave Palestine when the Israelis started killing Palestinians and occupying their land. The Europeans were fed up with Jews in their countries then and Belfour decided to relieve Europe by promising the land of Palestine to the Jews as their Holy Land.
A lot of Jews starting coming to Palestine as the UK was promising them a great life in a land of their own. Unfortunately, the US and many European countries brainwash their people in the media by showing Israel as the victim. I suggest you revise your facts and read more before making judgments.
