Access to
Jordan's only seaport of
Aqaba and to
Israel's only
Red Sea seaport of
Eilat is through the Gulf of Aqaba, which gives the Straits of Tiran strategic importance. In 1967, 90% of Israeli oil passed through the Straits of Tiran, making it a target of Egyptian blockade during the
Arab League boycott of Israel. In May 1967, Israeli Prime Minister
Levi Eshkol repeated declarations that Israel had made in 1957, saying that closure of the Straits of Tiran would be an act of war. Egypt then blockaded the straits on May 22, 1967, and oil tankers that were due to pass through the straits were required to submit documents ensuring their cargo was not destined for an Israeli port. At that time, Israel viewed the Straits of Tiran as a vital interest as it is where Israel received vital imports, mainly oil from Iran, and a blockade threatened Israel's ability to develop the
Negev. In May 1967, Major-General
Indar Jit Rikhye was the Commander of the
United Nations Emergency Force (UNEF) in the Sinai Peninsula when Egypt deployed its own troops in that territory and demanded that Rikhye withdraw all of his troops. Rikhye did withdraw, including from the port at
Sharm El Sheikh adjacent to the straits. The subsequent closure of the Tiran Straits by Egypt was closely linked to the preceding UNEF withdrawal, because having the peacekeepers (rather than the Egyptian military) at Sharm El Sheikh was important for keeping that waterway open. Later in life, General Rikhye sought to downplay the importance that Israel attached to keeping that waterway open, saying that Israel's accusation in 1967 of a blockade was "questionable" given that an Israeli-flagged ship had not passed through the straits in two years, and that "The U.A.R. [Egyptian] navy had searched a couple of ships after the establishment of the blockade and thereafter relaxed its implementation". Egypt had initially requested UNEF withdrawal from locations other than Sharm El Sheikh, but
UN Secretary-General U Thant demanded an all-or-nothing withdrawal. The US president at the time,
Lyndon Johnson, said the following about closure of these straits being a cause of the
Six-Day War: "If a single act of folly was more responsible for this explosion than any other, it was the arbitrary and dangerous announced decision that the Straits of Tiran would be closed. The right of innocent, maritime passage must be preserved for all nations." == Bridge project ==
