The 1973 war convinced the Israelis of the necessity of negotiations with the Arabs. This unprecedented willingness, coupled with Sadat's diplomatic initiatives and intercession by the United States to break barriers of mistrust between Egypt and Israel, made possible the long series of discussions between both nations. The negotiations ultimately resulted in the 1978 Camp David Agreements, and the peace treaty between Egypt and Israel in 1979. Thus, without resorting to another major war, Sadat had been able to regain the Sinai through diplomatic means.
