Yes. The resolution passed unanimously by the UN Security Council on November 22nd, 1967 established principles that became a guide for future Arab-Israeli Peace agreements. The second clause of this resolution calls for a “just settlement of the refugee problem,” the generic term “refugee” rather than “Palestinian refugee” was placed intentionally in the resolution to acknowledge that two refugee populations were created as a result of the Middle East conflict: one of Jews from Arab countries and one of Palestinians. The PLO in a letter to the UN General Assembly on October 15, 1968 rejected UN Resolution 242 saying that “the implementation of said resolution will lead to the loss of every hope for the establishment of peace and security in Palestine and the Middle East region.”
