Despite the success of the embargo, the Arab forces faced military defeat. GENEVA ACCORDS. Egypt, Jordan, and ultimately Syria decided to participate in the Geneva Peace Conference , for the settle- ment of the conflict under the chair of the United States and the Soviet Union. All parties finally agreed to disengage forces by May 1974 in an agreement negotiated by then-United States Secretary of State Henry Kissinger. The subsequent Sinai I and II agreements returned much of the Sinai to Egypt. Israeli public uproar over the government's unpreparedness prompted Prime Minister Golda Meir to resign. Throughout the 1970s, an increasing number of Israelis began to settle in the occupied territories. On November 11,1976, the UN Security Council condemned this policy and demanded that Israel follow the Geneva Convention's rules regard- ing occupied territory. Although Prime Minister Yitzhak Rabin discouraged permanent West Bank settlement, the next government, under Prime Minister Menahem Begin invested money and effort in new settlements. CAMP DAVID ACCORDS. Eager to regain the Sinai, Sadat decided to seek unilat- eral peace with Israel. In November 1977, Sadat made a historic visit to Jerusalem and was officially welcomed. By September 1978, Begin and Sadat had forged an agreement with the help of US President Jimmy Carter at Camp David, the presiden- tial retreat in Maryland. The most successful and lasting stipulation was Israel's agreement to relinquish the Sinai in exchange for peace and full diplomatic rela- tions with Egypt. However, the stipulations concerning Israel's control of the West Bank and Gaza were more muddled. Sadat returned to Cairo content that Palestin- ians in the occupied territories would be granted full personal and territorial sov- ereignty within the next five years, whereas Begin maintained that nothing regarding the occupied territories had been agreed upon. After the Camp David Accords, early hopes that other Arab states would nego- tiate with Israel evaporated. In October 1981, in response to cracking down on fundamentalists, Sadat was assassinated and Hosni Mubarak, Sadat's Vice Presi- dent, was sworn in. Though sticking to the terms of the 1979 Camp David peace treaty, Mubarak kept the diplomatic air cool for most of the 1980s in an attempt to reintegrate Egypt with the rest of the Arab world. In 1984, Egypt restored rela- tions with the Soviet Union and was readmitted to the Islamic Conference, and by 1988, the Arab League had invited Egypt to rejoin and dropped demands that it sever its ties with Israel. THE ISRAELI INVASION OF LEBANON. On June 6, 1982, Israel invaded Lebanon. The attack, dubbed "Operation Peace for Galilee" by Defense Minister Ariel Sharon, was supposedly intended to create a protective buffer zone; it is gener- ally accepted, however, that the attack aimed to wipe out PLO forces operating there that had been attacking northern Israel.
