Israeli passage through the Suez Canal and Straits of Tiran was restricted by Egypt, in cooperation with Saudi Arabia, for much of the time between the 1948 Arab–Israeli War and the 1967 Six-Day War. Since the Egypt–Israel peace treaty of 1979, Israel has enjoyed freedom of navigation through the Suez Canal and the Straits of Tiran.
Egypt was one of the main Arab countries that invaded Israel after the Israeli Declaration of Independence, sparking the 1948 Arab–Israeli War. Although the Egyptians were defeated during this conflict, they managed to occupy what would become known as the Gaza Strip and did not recognize Israel as a sovereign state following the 1949 Armistice Agreements. The ceasefire between the two countries was being tested by the Egypt-based Palestinian Fedayeen insurgency, which was prompting Israeli reprisal operations. Egypt had closed the Suez Canal and the Straits of Tiran to all Israeli vessels in 1949, preventing imports and exports amidst Israel's austerity period. Tensions worsened as the Egyptians gradually strengthened their blockade of Israel, culminating in the Suez Crisis of 1956, during which Israel invaded Egypt's Sinai Peninsula in order to force a re-opening of the blockaded waters, though the Suez Canal was closed until 1957, when Israeli troops withdrew from Egypt. However, in the mid-1960s, Egypt imposed another blockade against Israel, which had declared that any such action would be a casus belli. The Egyptian military subsequently mobilized along Israel's border and expelled the United Nations Emergency Force, leading to the Six-Day War of 1967, which ended in an Egyptian defeat and the Israeli occupation of the Sinai Peninsula. Following the outbreak of hostilities in 1967, the Suez Canal was closed until 1975. In 1973, Egypt attempted to retake the Sinai Peninsula by force, triggering the Yom Kippur War; although the initial Egyptian offensive was successful, the conflict ended in an Israeli victory. In 1979, Egypt became the first Arab country to recognize Israel as part of a bilateral peace treaty, in exchange for which Israel withdrew from the Sinai Peninsula in 1982. The two countries have remained at peace since 1979, and the overall Egypt–Israel relationship is generally cordial and cooperative.
Maritime routes through the Straits of Tiran serve the Israeli city of Eilat, which is situated on the Gulf of Aqaba. However, this had limited economic relevance prior to 1956—construction on the Port of Eilat began in 1952, and it was only able to take ocean-going vessels from March 1956 onward. Prior to this point, an average of just two vessels travelled to Eilat on an annual basis.
History 1948–1951 At the start of the Arab–Israeli conflict in May 1948, Egypt blocked passage through the Suez Canal to Israeli-registered ships and to ships (Israeli or otherwise) carrying cargo to and from all Israeli ports. Since all land trade routes were blocked by other Arab states, Israel's ability to trade with East Africa and Asia, mainly to import oil from the Persian Gulf, was severely hampered. The Straits of Tiran and Suez Canal remained formally closed to Israeli vessels from the creation of Israel in 1948 until the Suez Crisis in 1956.
On 10 March 1949, Israeli forces took control of the area around the abandoned coastal police station of Umm al-Rashrash, where Israel later built the town of Eilat, as part of Operation Uvda, giving Israel access to the Gulf of Aqaba, which leads to the Straits of Tiran. The capture of Umm Rashrash, and thus Israeli access to the Gulf of Aqaba, was not subject to the Egyptian–Israeli armistice agreement, because that agreement had been signed three weeks prior on 24 February 1949. In December 1949 Egypt started to erect military installations on the uninhabited islands of Tiran and Sanafir and the Sinai coast opposite the islands to control the straits. The Egyptian Government communicated its accord with Saudi Arabia to the UK and the US on 30 January and 28 February 1950 respectively:
Israel first complained to the United Nations about Egyptian interference with shipping in June 1951; at this time the complaints were solely about the Suez Canal, as the Straits of Tiran were not relevant (the Port of Eilat did not open until 1952, and even then only to small boats). Israel also prepared military plans to force Egypt to let their ships pass, should diplomatic means prove to be unsuccessful. On 1 September 1951, the United Nations Security Council Resolution 95 was passed; it called upon Egypt to "terminate the restrictions on the passage of international commercial shipping and goods through the Suez Canal wherever bound". Although the resolution referred only to the Suez, Israel believed it would induce a change in Egyptian policy on the Straits of Tiran.
During this period the Straits had limited relevance to Israel's economy; between 1949 and 1956, only ten ships destined for Eilat passed through the Straits of Tiran, all of them having a foreign maritime flag.
1952–1955 On 25 June 1952, Eilat was declared to have a port – albeit one with very basic facilities; a fully functioning port would be developed over the coming years.
Between 1949 and late 1953, Egypt allowed non-strategic goods to pass unhindered to Israel.
On 10 July 1955, David Ben-Gurion, then Israel's Minister of Defence, announced that the port of Eilat was nearly complete; it would be completed by mid-1956. Egyptian intervention was increased further in 1955, after the killing of 38 Egyptian soldiers on 28 February 1955 in Operation Black Arrow and the killing of 72 Egyptian soldiers on 31 August 1955 in Operation Elkayam. In response to the latter event, on 5 September 1955, Egypt tightened its blockade of Israeli shipping through the Straits of Tiran, and closed the airspace above it. In response, Israel stated on 13 September 1955 that "Israel is determined to protect the rights of free passage through this international channel at whatever time and by whatever methods it sees fit"; and on 29 September 1955, two weeks after delivery of this statement, declared that should the blockade remain in effect, Israel would not hesitate to use force.
1956: Suez Crisis
In the period prior to what became known as the Suez Crisis, on 13 October 1956 United Nations Security Council Resolution 118 was released, stating that "There should be free and open transit through the Canal without discrimination, overt or covert – this covers both political and technical aspects".
1957–1966 Egypt was required by the international community to open the waterways to all shipping following the conflict, although it never acceded to doing so with respect to Israeli shipping, due formally to its non-recognition of the country.
Following the Suez Crisis, Israel made a number of statements confirming the importance of shipping access – these statements were used as political justification a decade later on the outbreak of the 1967 war. On 1 March 1957, Israel's Foreign Minister Golda Meir declared at the UN General Assembly that any closure of the Straits of Tiran would be considered by Israel as an act of war, or justification for war:
However, in a less widely publicised statement ten days later on 11 March 1957, Nasser announced that he would not permit passage of Israeli ships either through the Gulf of Aqaba or the Suez Canal. However, both Egypt and Israel subsequently and unofficially pulled back from their formal positions.
In practice, these restrictions had limited economic relevance; during the ten years from 1957 to 1967, only one Israeli-flagged ship per month and four foreign-flagged ships per month arrived at Eilat. Although by the end of the decade, Israeli oil shipments from Pahlavi Iran became important.
1967: Six-Day War
In 1967, as tensions rose between Egypt and Israel, Israel reiterated declarations made in 1957 that any closure of the Straits would be considered an act of war.Cohen, Raymond. (1988), p. 12. On 23 May, Nasser shut the Straits of Tiran to Israeli vessels. Israeli Prime Minister Eshkol repeated declarations that Israel had made in 1957, saying that closure of the Straits of Tiran would be an act of war.Neff, David. Warriors for Jerusalem: the six days that changed the Middle East, p. 88 (Simon & Schuster, 1984): "In separate messages to the leading maritime powers, Eshkol warned: 'Israel would stop short of nothing to cancel the blockade. It is essential that President Nasser should not have any illusions.'""Statement to the General Assembly by Foreign Minister Meir, 1 March 1957" (Israel Ministry of Foreign Affairs): "Interference, by armed force, with ships of Israeli flag exercising free and innocent passage in the Gulf of Aqaba and through the Straits of Tiran will be regarded by Israel as an attack entitling it to exercise its inherent right of self-defence under Article 51 of the Charter and to take all such measures as are necessary to ensure the free and innocent passage of its ships in the Gulf and in the Straits." Then, on May 22, Egypt responded by announcing, in addition to the UN withdrawal,"Part 4: The 1967 Six Day War", NPR: "In the spring of that year , the Soviet Union had led the radical government in Damascus to believe that Israel was planning to invade Syria. Syria shared this misinformation with Nasser. The Egyptian leader closed the Gulf of Aqaba to shipping, cutting off Israel's primary oil supplies. He also ordered United Nations peacekeepers to leave the Sinai Peninsula. And he sent scores of tanks and hundreds of troops into the Sinai toward Israel." that the Straits of Tiran would be closed to "all ships flying Israeli flags or carrying strategic materials", with effect from May 23."Egypt Closes Gulf Of Aqaba To Israel Ships: Defiant move by Nasser raises Middle East tension", The Times, p. 1 (May 23, 1967). In order to enforce the blockade, Egypt falsely announced that the Tiran straits had been mined.Shlaim, Rogan 2012 p. 64 90% of Israeli oil passed through the Straits of Tiran. Oil tankers that were due to pass through the straits were delayed.
According to Sami Sharaf, Egypt's Minister of State for Presidential Affairs, Nasser knew that the decision to block the Tiran straits made the war "inevitable". Nasser stated, "Under no circumstances can we permit the Israeli flag to pass through the Gulf of Aqaba." The closure of the Tiran Straits was closely linked to the previous withdrawal of the UN peacekeepers, because having the peacekeepers (rather than the Egyptian military) at Sharm El Sheikh was important for keeping that waterway open.
In his speech to Arab trade unionists on May 26, Nasser announced: "If Israel embarks on an aggression against Syria or Egypt, the battle against Israel will be a general one and not confined to one spot on the Syrian or Egyptian borders. The battle will be a general one and our basic objective will be to destroy Israel.".Seale 1988, p. 131 citing Stephens 1971, p. 479.
Nasser publicly denied that Egypt would strike first and spoke of a negotiated peace if Israel allowed all Palestinian refugees the right of return, and of a possible compromise over the Straits of Tiran.Egypt: A Country Study, U.S. Library of Congress
As a result of the Six-Day War, on 7 June, Israel announced that the Straits of Tiran constituted an international waterway open to all ships without restriction.
