Not in 1948 when twice as many Arabs as Jews lived between the River and the sea:Nope, Arab Palestine was supposed to be Jordan, where currently majority of Jordanians are PALESTINIANS. Ha ha ha, what a fraud.
Jews were given 55% of the land between the River and the sea by the UN in violation of its Charter. Arabs objected to the subsequent ethnic cleansing, and Jews took another 15%. In '67 Israel stole the remaining 22% of Palestine.
The UN plan gave the Jews nothing. It recommended 3 tiny, easily cut-off Bantustans most of which was Negev desert and none of which was anywhere near Jerusalem. Nevertheless the Jews accepted the piss-poor plan and the Arabs threw a violent hissy fit. Quite the surprise, eh? The Arabs would love another shot at UN 181 but that ship has sailed.
