Sinai

The Sinai Peninsula is a triangular landmass of approximately 60,000 square kilometers connecting the African and Asian continents, bounded by the Suez Canal and the Gulf of Suez to the west and the Gulf of Aqaba to the east. It is administered as part of Egypt but is geographically distinct from the African mainland. The peninsula's terrain ranges from the desert coastal plains of the north to the red granite mountains of the south, including Mount Sinai (Jabal Musa), significant in the Abrahamic religious traditions as the site of the Mosaic covenant. The Sinai's permanent civilian population is approximately 600,000, largely concentrated in the northern coastal strip.¹

Six-Day War Capture (1967)

Israeli forces captured the entire Sinai during the Six-Day War of June 5-10, 1967, in a rapid armored advance following the Israeli Air Force's preemptive destruction of the Egyptian air force on the morning of June 5. The advance reached the Suez Canal by June 8, closing the Canal to international shipping until 1975. Israel established military administration of the Sinai and developed infrastructure including roads, airfields, and eventually civilian settlements - particularly on the Gulf of Aqaba coast at Sharm el-Sheikh.

The Bar-Lev Line - a series of fortified positions along the Canal's eastern bank constructed 1968-1969 - was Israel's primary defensive line. Its construction reflected a strategic decision to hold the Canal as a defensive barrier rather than return it to Egypt in exchange for a negotiated settlement.

The 1973 Yom Kippur War and Intelligence Failure

The Sinai was the western theater of the October 1973 Yom Kippur War, which began with a coordinated Egyptian-Syrian surprise attack on October 6, the Jewish holiday of Yom Kippur. Egyptian forces crossed the Canal in a meticulously planned deception operation, using high-pressure water hoses to breach the sand fortifications of the Bar-Lev Line, and advanced into the Sinai before Israeli reserves could mobilize.

The Egyptian crossing constituted one of the most consequential intelligence failures of the Cold War for both Israel and the CIA. Egyptian President Anwar Sadat had executed an elaborate strategic deception - including a history of military mobilizations later stood down - that trained Israeli and U.S. intelligence analysts to discount Egyptian military movements as political signaling rather than genuine preparations for war. The Israeli military intelligence directorate (Aman) maintained a doctrine (known informally as "the Concept") that Egypt would not attack until it had acquired certain weapons systems. CIA Director William Colby later acknowledged that finished CIA intelligence had failed to warn of the imminent attack and that the Agency had relied excessively on Israeli assessments.²

Israeli forces stabilized the Sinai front by October 9-10 and counterattacked, crossing the Canal on October 15-16 and encircling the Egyptian Third Army by the ceasefire of October 25.

Camp David and Return to Egypt

The 1978 Camp David Accords negotiated by U.S. President Jimmy Carter between Sadat and Israeli Prime Minister Menachem Begin provided for Israeli withdrawal from the entire Sinai in exchange for Egyptian recognition of Israel. The withdrawal was completed in stages, with full withdrawal completed April 25, 1982, including the demolition of the Israeli settlement at Yamit. A multinational peacekeeping force (the Multinational Force and Observers, MFO) was established to monitor the treaty's military provisions and has operated continuously since.¹
