All been hashed out elsewhere but CarolC's last post:

"No part of Mandate Palestine was ever given to Jews to be a Jewish state prior to the partition plan. Jews were to be able to make their home in the area that was allotted for that purpose, but they were not supposed to make a Jewish state there."

Very true up until the Peel Commission's Report of 1937 where after 16 years of unprovoked Arab attacks Jews in Palestine the British Government finally concluded that the two groups could not co-exist peacefully in one state. This was in the middle of what was known to the Arabs of Palestine as the "Great Revolt". From that date forward the plan was always for a two-state solution. The Peel Commission proposals were taken further by the United Nations who presented their own version of it in 1947. the Jews accepted it, the Arabs rejected it.

"All of the Arabs in all of Mandate Palestine were supposed to be able to remain where they were and to be co-equals with any Jews who chose to make their home there."

Again true CarolC, those Arabs who wanted to stay in what was going to become Israel were quite at liberty to stay. But Arab rejection of the UN Partition Plan of 1947 resulted in a war. Had the Arabs accepted the plan in 1947, there would have been no displaced people, which means today there would be no "Right of return" issue to settle, and the Arabs would have everything they say they are fighting for now.
