Signed by the Palestinian Liberation Organization (PLO) and Israel in September of 1993, the Declaration of Principles (DOP) calls for a phased peace process, including permanent settlement to the Israeli-Palestinian conflict based on United Nation Resolutions 242 and 338. The DOP is complemented by a previous exchange of letters between Israeli Prime Minister Yitzhak Rabin and PLO Chairman Yasser Arafat, in which Israel recognized the PLO as the representative of the Palestinian people and the PLO recognized Israel’s right to exist in peace and security. The DOP was the first formal agreement signed by official representatives of the State of Israel and the PLO. See Fischbach, Michael R. “Oslo Agreements.” Philip Mattar, ed.
