Sinai Interim Agreement (Sinai II)

The Sinai Interim Agreement grew directly out of the unfinished diplomatic business of the October 1973 Yom Kippur War. Kissinger's shuttle diplomacy had already produced an Israel-Egypt disengagement agreement in January 1974 and an Israel-Syria agreement in May 1974, establishing a pattern of incremental, U.S.-mediated steps toward stabilization rather than a comprehensive settlement.[8][9] The UN Emergency Force II (UNEF II), established in October 1973 to supervise the Yom Kippur War ceasefire, was stationed first in the Suez Canal area and later in Sinai, with its headquarters in Ismailia. It was charged with supervising the redeployment of forces and controlling the buffer zones created under the disengagement accords.[10]

Egyptian President Anwar Sadat persuaded President Gerald Ford and Kissinger to pursue a further agreement over Sinai, and negotiations began in earnest.[3] The process was described as exhausting and conducted mainly between the United States and Israel, with Egypt also involved, lasting approximately 18 months after Israeli Prime Minister Golda Meir had responded positively to an earlier message from Sadat.[5] Prime Minister Yitzhak Rabin, who led Israel through the bulk of the negotiations, was willing to withdraw from significant parts of Sinai, allow Egyptian forces to advance to positions at the western entrances to the Mitla and Giddi Passes, and relinquish the Abu Rudeis oil fields.[6] His core demand, however, was a formal Egyptian commitment to non-belligerency. Sadat offered only "non-use of force" rather than a peace treaty, and Rabin rejected surrendering the strategically important passes for that guarantee alone.[6]

Kissinger undertook a 15-day shuttle-diplomacy effort to bridge the gap. After two weeks of travel between Israel and Egypt, he abandoned the effort on March 22, 1975, with negotiations at a stalemate.[6] Ford concluded that Israel had been less forthcoming than Egypt and called for a formal reassessment of U.S. policy toward Israel, prompting an outcry in the Senate.[3] Seventy-six senators sent Ford a letter on May 22 urging support for Israel's military and economic needs; the State Department records that Ford backed away from the reassessment during the early summer.[6][3] The administration also froze Israel's request for F-15 aircraft and delayed a promised shipment of Lance missiles during the confrontation.[6]

By August 1975, a path forward appeared within reach.[3] The breakthrough came partly from a proposal—attributed in an account cited by former Israeli prime-ministerial adviser Yehuda Avner to Defense Minister Shimon Peres—to station American military personnel, publicly described as "technicians," at key positions in the passes.[6] Egypt conceded that Israeli "technicians" would remain at the Um Hashiba alert station overlooking the passes, and Israel agreed to present the American-personnel proposal publicly as a U.S. initiative rather than an Israeli one.[6] These arrangements allayed Israeli concerns about the strategic consequences of withdrawing from the passes and allowed Sadat to demonstrate progress without signing a formal non-belligerency declaration.[6]

The agreement and its annex were initialed on September 1, 1975, by Israeli representatives in Jerusalem and Egyptian representatives in Alexandria.[1][2] The formal signing ceremony took place in Geneva on September 4, 1975.[1][2] The Knesset ratified the agreement on September 3; Ma'ariv reports a vote of 70 in favor and 43 against, with Menachem Begin leading the parliamentary opposition.[6][11] The Israeli government led by Prime Minister Yitzhak Rabin had approved the accord before it was transmitted to the Knesset.[11]

The agreement entered into force upon the signature of the Protocol and was to remain in force until superseded by a new agreement.[1][2] Its implementation was to be carried out by a military working group that would determine the phasing of Egyptian and Israeli troop redeployments.[2] The first phase—the transfer of the Abu Rudeis and Ras Sudar oil fields and installations to Egypt—was to begin within two weeks of the Protocol's signature and be completed no later than eight weeks after commencement.[2] Full redeployment of forces was to be completed within five months of the Protocol's signing.[2]

The oil fields and the Israeli settlement of Shalhevet were evacuated by the end of November 1975, with the transfer of the oil fields formally completed in early December.[12] Contemporary reporting stated that Israel had extracted approximately 32 million tons of oil from Abu Rudeis since the Six-Day War, valued at roughly 2.5 billion dollars.[12] The handover involved practical interdependencies: Egypt would need water from Israel to sustain operations, while Israel relied on the Abu Rudeis power station to operate its own water wells.[12] The field handover to American technicians was briefly delayed because of wireless communications difficulties with Cairo.[12]

Public Law 94-110, approved on October 13, 1975, authorized implementation of the American early-warning proposal in Sinai. It capped U.S. civilian personnel at no more than 200, required their immediate removal if hostilities broke out, limited participation to volunteers, and required the President to report to Congress at least every six months.[4]

The agreement established a new set of military lines in Sinai. Israeli forces were required to deploy east of Lines J and M, while Egyptian forces were to remain west of Line E.[1][13] The areas between Lines E and F and between Lines J and K were designated as zones with strict limitations on armaments and forces.[1][13] The area between Lines E and J constituted a UN buffer zone in which UNEF II would continue its functions under the mandate of the 1974 agreement.[1][13] In the area south of Line E and west of Line M, no military forces of either party were to be stationed, and UNEF II was assigned responsibility for ensuring the absence of military or paramilitary forces, fortifications, and military installations.[2]

The annex set precise caps for the limited-forces zones: no more than eight infantry battalions, 75 tanks, 72 artillery pieces including heavy mortars, and 8,000 personnel on each side.[2] Artillery range was limited to 12 kilometers, and both parties agreed not to station weapons capable of reaching the other side's line.[2] Anti-aircraft missiles were barred within 10 kilometers east of Line K on the Israeli side and west of Line F on the Egyptian side, with UNEF II assigned inspection responsibilities to verify compliance.[2]

Israel withdrew to the eastern ends of the Mitla and Giddi Passes under the agreement.[14] The previous UN buffer zone became Egyptian territory, and a new UN-monitored buffer zone was created in the vacated area.[14] Israel also relinquished the Abu Rudeis and Ras Sudar oil fields.[14] Egypt conceded that non-military cargoes destined for or coming from Israel could pass through the Suez Canal.[2][14]

Article I described the January 18, 1974, Egyptian-Israeli agreement as a first step toward a just and durable peace under UN Security Council Resolution 338 and committed both parties to resolve the conflict by peaceful means rather than military force.[1] Both countries undertook not to threaten or use military force or impose a military blockade against one another, to observe the ceasefire on land, sea, and air, and to refrain from military or paramilitary actions.[1] Egypt had rejected Israel's original demand that the agreement include the term "non-belligerency"; the compromise language on peaceful resolution was accepted instead.[5] The agreement explicitly characterized itself as a significant step toward peace but not a final peace agreement, and called for continued negotiations toward a final settlement within the Geneva Peace Conference framework and in accordance with Resolution 338.[2]

The agreement made UNEF II's continued role essential and provided for its mandate to be extended annually.[1][15] A joint commission was established for the agreement's duration, operating under the aegis of the Chief Coordinator of UN Peacekeeping Missions in the Middle East, to consider problems arising from the agreement and assist UNEF II in carrying out its mandate.[1][15] The annex also provided for U.S. aerial reconnaissance over the area between Lines F and K, normally once every seven to ten days. Either party or UNEF II could request an earlier mission, and the United States was to share mission results with Egypt, Israel, and the UN coordinator.[2]

One of the most distinctive elements of Sinai II was the establishment of a joint early-warning system staffed in part by American civilians. The arrangement included Egyptian- and Israeli-operated strategic surveillance stations, each permitted no more than 250 technical and administrative personnel.[2] Three U.S.-operated watch stations were placed in the Mitla and Giddi Passes, supported by three unmanned electronic sensor fields.[2][16] The U.S. civilian personnel at these stations were assigned to report specified movements or departures from authorized surveillance roles to Egypt, Israel, and UNEF II.[2]

A legal analysis of the agreement noted that three early-warning stations were established in the northernmost buffer zone: one Egyptian, one Israeli, and one manned by U.S. civilians, in an area that permitted no forces of either party, only UN forces.[17] Public Law 94-110 formally authorized the proposal on October 13, 1975, capping American personnel at no more than 200 civilians performing specified noncombat functions, restricting participation to volunteers, and requiring their immediate withdrawal if hostilities erupted between Egypt and Israel.[4] The law also required semiannual presidential reports to Congress while the mission continued.[4]

The United States was authorized to withdraw its personnel if it judged their safety jeopardized or their role no longer necessary, with advance notice required in the latter case to allow the parties to consider alternatives.[2] Kenneth W. Stein characterized the placement of 200 Americans in Sinai as a physical restraint against renewed war.[18] The State Department's account confirms that the agreement committed U.S. resources to three manned stations and three unmanned electronic sensor fields in Sinai.[3]

Separately from the bilateral Egypt-Israel agreement, Israel obtained a series of commitments from the United States in a Memorandum of Understanding.[6] The United States promised not to recognize the Palestine Liberation Organization unless it first recognized Israel's right to exist and accepted UN Security Council Resolutions 242 and 338.[6][19] The United States also committed not to push Israel into a similar disengagement process with Syria and assured Israel that the next Egypt-Israel agreement would be a full peace treaty rather than another interim step.[6]

President Gerald Ford gave Prime Minister Rabin a letter dated September 1, 1975, stating that the United States had not developed a final position on borders and would give great weight to Israel's position that any peace agreement with Syria must be predicated on Israel remaining on the Golan Heights.[15] A separate U.S. memorandum included support for Israel's full right to free and unhindered passage through the Bab el-Mandeb and Gibraltar straits.[20]

Ma'ariv reports that the prospect of substantially increased U.S. military and economic aid was one of the principal reasons Rabin's government agreed to the interim arrangement and that additional agreements, some secret, covered military, political, and economic assistance.[11] A JCFA analysis argues that the security package prepared during the negotiations upgraded the Israeli Air Force from Skyhawks and Phantoms to F-15s and F-16s as compensation for Israel's withdrawal from the strategically valued passes.[13] The same analysis reports that U.S. aid to Israel stood at 823 million dollars in 1975, rose to 2.36 billion dollars in 1976 following Sinai II, and fell to 1.78 billion dollars in 1977, interpreting the 1976 surge as an agreement-related one-year package.[13]

Ma'ariv also reports that Egypt gave the United States a written commitment not to intervene in a war between Israel and Syria if Syria initiated hostilities. The same account describes the arrangement as deepening the rift between Cairo and Damascus and accelerating Egypt's shift toward the American diplomatic orbit.[11]

The implementation of Sinai II proceeded according to the agreement's phased schedule. UNEF II took on an expanded supervisory role, controlling the new buffer zones, verifying force-limitation compliance through regular inspections, and ensuring the absence of military forces in the southernmost demilitarized area.[10][2] Egyptian and Israeli civilian-police arrangements were worked out in the Protocol, and the annex allowed Egyptian civilians and third-country oil-field personnel to enter, leave, work, and live in the designated area subject to buffer-zone and UN-post exceptions.[2] Access by air and sea was limited to specified unarmed civilian vessels and aircraft, and Israel undertook to leave existing civilian installations and infrastructure intact upon withdrawal.[2]

The agreement permitted non-military cargoes destined for or coming from Israel to pass through the Suez Canal, a practical concession that accompanied the broader military disengagement.[1][2]

Ma'ariv's account describes the agreement as contributing to a rupture between Egypt and Syria and as cementing Egypt's reorientation toward the United States.[11] A JCFA analysis presents the agreement as part of a broader shift toward bilateral, U.S.-mediated negotiations, despite Rabin's stated preference for a comprehensive Arab-Israeli process under the Geneva Conference framework.[21] The analysis attributes the eventual separate track in part to Egypt's determination to move toward peace even without Syrian agreement.[21]

Sinai II occupies a central place in the history of Arab-Israeli peacemaking and in the evolution of the U.S.-Israel strategic relationship. The INSS characterizes it as having paved the way for the 1979 Egypt-Israel Peace Treaty and transformed the relationship between Washington and Jerusalem.[6] The Jerusalem Center for Security and Foreign Affairs places the 1975 agreement in a sequence followed by the 1978 Camp David negotiations and Accords and the 1979 peace treaty.[7] Ma'ariv credits the period of calm created by the agreement with helping make Anwar Sadat's 1977 visit to Jerusalem possible.[11]

The agreement is also notable for combining territorial withdrawal with security guarantees and American assurances. Kenneth W. Stein emphasized the physical placement of 200 Americans in Sinai, describing the U.S. presence as a restraint against renewed war.[18][4] The early-warning architecture—Egyptian, Israeli, and American stations alongside unmanned electronic sensor fields and regular U.S. aerial reconnaissance—created a multilayered monitoring system intended to detect prohibited movements and support compliance.[2]

The U.S. commitment not to recognize the PLO unless it accepted Israel's right to exist and UN Resolutions 242 and 338 was a significant American policy commitment.[6][19] The Memorandum of Understanding included pledges concerning Syria, PLO recognition, and the character of the next Egyptian-Israeli agreement.[6]

The Israeli government's historical account described the agreement as an important step toward a just and sustainable peace.[14] Sinai II formed part of the sequence leading to the 1978 Camp David Accords and the 1979 peace treaty, while its combination of withdrawal, monitoring arrangements, and U.S. assurances foreshadowed elements of the diplomacy that followed.[6][7]

INSS states that Egypt accepted the "peaceful means" clause under pressure after rejecting Israel's preferred term, "non-belligerency." Because the official accord omitted a non-belligerency declaration, the degree and meaning of that pressure remain matters of interpretation in accounts of the negotiations.[5][1] Ford blamed Israel for the March 1975 stalemate and ordered a reassessment of U.S. policy. INSS records the subsequent letter from 76 senators, while the State Department says the Senate outcry preceded Ford's retreat from the reassessment; the precise causal weight of congressional pressure is difficult to isolate.[6][3]

The proposal to place American "technicians" in the passes, as recounted through Yehuda Avner's account and attributed to Defense Minister Shimon Peres, illustrates the diplomatic opacity surrounding the agreement. Israel agreed to present the proposal publicly as an American initiative rather than an Israeli one.[6] Kenneth W. Stein later characterized the American presence as a physical restraint against renewed war, an attributed assessment of the arrangement's effect.[18]

A JCFA source characterizes the 1975 agreement as having "terminated the state of belligerency" between Egypt and Israel, while the agreement's own text explicitly described it as an interim step and not a final peace.[7][2] Sinai II should therefore not be conflated with the 1979 Egypt-Israel Peace Treaty, which established the formal state of peace. Ma'ariv describes the interim agreement as deepening the rupture between Egypt and Syria and shifting Egypt toward the United States; these are the source's interpretations of its broader regional consequences.[11]
