The onus is on you. Your claim is so ridiculous that you need to support it with facts. "Legal letters and maps for the legal title to Jerusalem, Judea and Samaria"??!!! The Balfour Declaration spoke of the estblishment of a Jewsih homeland in Palestine that would not put in jeaopardy the well being of the non-Jewish communities. It did not "title" what you call Eretz Yisrael to the Jewish People. These letters and maps you refer to are not the basis for negotiations between Israel and the palestinians. No international jurist would concur that they are legitimate documents that exclude any collective rights of the Palestinian population.
