On January 18, 1974, following the October 1973 War, Egypt and Israel negotiate a separation of forces agreement, known as Sinai I. Accompanying this disengagement agreement is a ten point Memorandum of Understanding between Israel and the US, which is meant to assure Israel of American monitoring of the agreement. For Arab-Israeli negotiations, this MOU sets a valued precedent; it enshrines Washington as the key intermediary to the exclusion of Europe, the UN and the USSR, and makes Washington the ‘umpire’ in assuring implementation of the disengagement agreement’s provisions.
