For 60 years the bureaucrats of UNRWA, by countenancing the Arab states' refusal to re-settle the original, 1948 Arab refugees, refugees from a war which the Arabs started, have protracted the Arab-Israeli conflict.

Save the world the never-ending expense of funding UNRWA, and speed up Arab-Israeli peace.
