Step-by-step explanation:
Events of September 1978 Involving Egypt, Israel, and the U.S.
In September 1978, a significant diplomatic breakthrough occurred as a result of the Camp David Accords, a series of negotiations that took place over thirteen days at the presidential retreat in Camp David, Maryland. These negotiations led to a historical peace agreement between Egypt and Israel, brokered by U.S. President Jimmy Carter. On September 17, 1978, Egypt, represented by President Anwar Sadat, and Israel, represented by Prime Minister Menachem Begin, signed the Camp David Accords at a ceremony at the White House. Consequently, Egypt officially recognized the State of Israel and agreed not to invade it, while Israel agreed to return the Sinai Peninsula to Egypt. The successful brokers of peace, Sadat, Begin, and Carter, each received the Nobel Peace Prize for their efforts.
This remarkable event followed years of conflict between Egypt and Israel, including the Yom Kippur War, which began on October 6, 1973, when Egypt and Syria launched a surprise attack. Despite their initial successes, both Egypt and Syria were ultimately repelled by Israeli forces. The difficult path to peace was set in motion as Egypt sought to regain the Sinai Peninsula without further warfare, shifting its approach by expelling Soviet advisers and beginning discussions with the U.S. The Camp David Accords represented a significant step towards lasting peace in the region and established a precedent that peace between an Arab nation and Israel was possible.
