The Palestinian Arabs were not responsible in some bizarre way for what befell them in 1948. Their responsibility was very direct and simple.
In defiance of the will of the international community, as embodied in the UN General Assembly Resolution of November 29th, 1947 (No. 181), they [Arabs] launched hostilities against the Jewish community in Palestine in the hope of aborting the emergence of the Jewish state and perhaps destroying that community. But they lost; and one of the results was the displacement of 700,000 of them from their homes.
...on the local level, in dozens of localities around Palestine, Arab leaders advised or ordered the evacuation of women and children or whole communities, as occurred in Haifa in late April, 1948. And Haifa's Jewish mayor, Shabtai Levy, did, on April 22nd, plead with them to stay, to no avail.
Most of Palestine's 700,000 "refugees" fled their homes because of the flail of war (and in the expectation that they would shortly return to their homes on the backs of victorious Arab invaders).
The displacement of the 700,000 Arabs who became "refugees" - and I put the term in inverted commas, as two-thirds of them were displaced from one part of Palestine to another and not from their country (which is the usual definition of a refugee) - was not a racist crime but the result of a national conflict and a war, with religious overtones, from the Muslim perspective, launched by the Arabs themselves.
However, you have the intelligence of Matt Damon!!!
