In 1978 Begin, aided by Foreign Minister Moshe Dayan and Defense Minister Ezer Weizman, came to Washington and Camp David to negotiate the Camp David Accords, leading to the 1979 Egypt–Israel Peace Treaty with Egyptian President, Anwar Sadat. Before going to Washington to meet President Carter, Begin visited Rabbi Menachem M. Schneerson for his advice. Under the terms of the treaty, brokered by US President, Jimmy Carter, Israel was to hand over the Sinai Peninsula in its entirety to Egypt. The peace treaty with Egypt was a watershed moment in Middle Eastern history, as it was the first time an Arab state recognized Israel's legitimacy whereas Israel effectively accepted the land for peace principle as blueprint for resolving the Arab–Israeli conflict. Given Egypt's prominent position within the Arab World, especially as Israel's biggest and most powerful enemy, the treaty had far reaching strategic and geopolitical implications.
