The UN had a partition plan but it was never implemented. Palestine was never partitioned.
And why was it not implemented? The Jews BEGGED the Arabs to stay in that part that was to be Israel. The Arabs REFUSED to form their own Government at the orders of the 5 Nations surrounding them. The intent was that those 5 Nations would drive the Jews out and partition the area amongst themselves.
Is that why Israel drove 300,000 Palestinian Christians and Muslims out of their homes and off their land BEFORE the 1948 war?
Sure thing.
