History of Israel. One of President Carter's greatest achievements was the peace accord between Egypt and Israel. This history of modern Israel notes this.
From the site:
In the years that followed, sporadic clashes continued along the cease-fire lines but guided by the U.S., Egypt, and Israel continued negotiations. In November 1977, Egyptian President Anwar Sadat made a historic visit to Jerusalem, which opened the door for the 1978 Israeli-Egyptian peace summit convened at Camp David by President Carter. These negotiations led to a 1979 peace treaty between Israel and Egypt, pursuant to which Israel withdrew from the Sinai in 1982, signed by President Sadat of Egypt and Prime Minister Menahem Begin of Israel.
