In 1967 Israel’s government was headed by Levi Eshkol, a politician said to be easygoing, weak and indecisive, who four years earlier had replaced the country’s founder, David Ben-Gurion, as prime minister. The Israeli public, tired of Ben-Gurion’s authoritarianism and constant exhortations to greater and greater sacrifice, had greeted Eshkol’s appointment with a sigh of relief. Israel’s chief Arab adversary at the time, Egyptian President Gamal Abdel Nasser, sought to take advantage of the Eshkol government’s reputed lassitude in order to annul Israel’s achievements in the 1956 Suez campaign: the demilitarization of the Sinai Peninsula and the opening of the Strait of Tiran to Israeli shipping.
