War of attrition
Following the 1967 Six-Day War, no serious diplomatic efforts tried to resolve the issues at the heart of the Arab–Israeli conflict. The 1967 Arab League summit formulated in September the "three no's" policy: barring peace, recognition or negotiations with Israel.[19] The Egyptian President Gamal Abdel Nasser believed that only military initiative would compel Israel or the international community to facilitate a full Israeli withdrawal from Sinai,[20][21] and hostilities soon resumed along the Suez Canal.
These initially took the form of limited artillery duels and small-scale incursions into Sinai, but by 1969, the Egyptian Army judged itself prepared for larger-scale operations. On March 8, 1969, Nasser proclaimed the official launch of the War of Attrition, characterized by large-scale shelling along the Suez Canal, extensive aerial warfare and commando raids.[20][22] Hostilities continued until August 1970 and ended with a ceasefire,[23] the frontiers remaining the same as when the war began, with no real commitment to serious peace negotiations.
Egyptian front
Israel's victory in the Six-Day War left the entirety of the Egyptian Sinai Peninsula up to the eastern bank of the Suez Canal under Israeli control. Egypt was determined to regain Sinai, and also sought to mitigate the severity of its defeat. Sporadic clashes were taking place along the cease-fire line, and Egyptian missile boats sank the Israeli destroyer INS Eilat on October 21 of the same year.
Egypt began shelling Israeli positions along the Bar Lev Line, using heavy artillery, MiG aircraft and various other forms of Soviet assistance with the hope of forcing the Israeli government into concessions.[24] Israel responded with aerial bombardments, airborne raids on Egyptian military positions, and aerial strikes against strategic facilities in Egypt.
The international community and both countries attempted to find a diplomatic solution to the conflict. The Jarring Mission of the United Nations was supposed to ensure that the terms of UN Security Council Resolution 242 would be observed, but by late 1970, it was clear that this mission had been a failure. Fearing the escalation of the conflict into an "East vs. West" confrontation during the tensions of the mid-Cold War, the American president, Richard Nixon, sent his Secretary of State, William Rogers, to formulate the Rogers Plan in view of obtaining a ceasefire.
In August 1970, Israel, Jordan, and Egypt agreed to an "in place" ceasefire under the terms proposed by the Rogers Plan. The plan contained restrictions on missile deployment by both sides, and required the cessation of raids as a precondition for peace. The Egyptians and their Soviet allies rekindled the conflict by violating the agreement shortly thereafter, moving their missiles near to the Suez Canal, and constructing the largest anti-aircraft system yet implemented at that point in history.[24][25]
The Israelis responded with a policy which their Prime Minister, Golda Meir, dubbed "asymmetrical response", wherein Israeli retaliation was disproportionately large in comparison to any Egyptian attacks.[24]
Following Nasser's death in September 1970, his successor, Anwar Al-Sadat, continued the ceasefire with Israel, focusing on rebuilding the Egyptian army and planning a full-scale attack on the Israeli forces controlling the eastern bank of the Suez Canal. These plans would materialize three years later in the Yom Kippur War. Ultimately, Israel would return Sinai to Egypt after the two nations signed a peace treaty in 1979.
