"land for peace" formula, calling for Israeli withdrawal from "territories" it had occupied in 1967 in exchange for peace with its neighbors. This was an important advance at the time, considering that there were no peace treaties between any Arab state and Israel until the Egypt–Israel peace treaty of 1979. "Land for peace" served as the basis of the Egypt–Israel Peace Treaty, in which Israel withdrew from the Sinai peninsula (Egypt withdrew its claims to the Gaza Strip in favor of the Palestine Liberation Organization). Jordan renounced its claims regarding the West Bank in favor of the Palestine Liberation Organization, and has signed the Israel–Jordan peace treaty in 1994, that established the Jordan River as the boundary of Jordan. Throughout the 1990s, there were Israeli-Syrian negotiations regarding a normalization of relations and an Israeli withdrawal from the Golan Heights. But a peace treaty was not made, mainly due to Syria's desire to recover and retain 25 square kilometers of territory in the Jordan River Valley which it seized in 1948 and occupied until 1967. As the United Nations recognizes only the 1948 borders, there is little support for the Syrian position outside the Arab bloc nor in resolving the Golan Heights issue. The UN resolution does not specifically mention the Palestinians. The United Kingdom had recognized the union between the West Bank and Transjordan. Lord Caradon said that the parties assumed that withdrawal from occupied territories as provided in the resolution was applicable to East Jerusalem. "Nevertheless so important is the future of Jerusalem that it might be argued that we should have specifically dealt with that issue in the 1967 Resolution. It is easy to say that now, but I am quite sure that if we had attempted to raise or settle the question of Jerusalem as a separate issue at that time our task in attempting to find a unanimous decision would have been far greater if not impossible." Judge Higgins of the International Court of Justice explained "from Security Council resolution 242 (1967) through to Security Council Resolution 1515 (2003), the key underlying requirements have remained the same – that Israel is entitled to exist, to be recognized, and to security, and that the Palestinian people are entitled to their territory, to exercise self-determination, and to have their own State. Security Council resolution 1515 (2003) envisages that these long-standing obligations are to be secured (...) by negotiation"
