The solution requires the Jews to stop stealing Arab land and water in Palestine. It requires Jews to stop incinerating Palestinian teens. It requires Jews to stop shelling hospitals in Gaza. Jews have been the problem in Palestine ever since 650,000 of them inflicted their nation upon 1.3 million Arabs in 1948; the solution arrives when the world holds the Jewish state to the same standard it applied to South Africa a generation ago.
I would say the real issue started when all Arabs tried to destroy the Jewish state, along with the Jews in it by attacking all together, and losing at the end.
Except the Jews began their ethnic cleansing of Palestinians months before their racist state lurched into existence. On 29 November 1947 the UN GA devised a partition of Palestine which gave Jews 56% of the land in spire of the fact Jews numbered about a third of the total Palestinian population. The British troops that had been occupying Palestine announced their departure was scheduled for the following May. By early 1948 months before the Zionist state came into existence, Jewish terrorists were seizing Arab land in Palestine. By July 1948 400,000 Arabs had been pushed off their land, and
al Nakba was just beginning.
An UN Mediator, Folke Bernadotte, lobbied for justice in Palestine by pointing out the innocent Arabs forced from their homes were denied their right of return while Jews from around the Middle East and Europe flocked into Israel and took the homes, businesses and possessions of the displaced Palestinians.
Bernadotte's initial report called for fixed boundaries, an economic union, and the right of return for Palestinian refugees.
A day later his motorcade was ambushed in Jerusalem, and he was shot dead by a Jew terrorist.
