The aims were to be threefold: to remove the threat, wholly or partially, of the Egyptian rmy in the Sinai, to destroy the framework of the fedaiyyun, and to secure the freedom of navigation through the straits of Tiran.
the removal of the Egyptian blockade of the Straits of Tiran at the entrance of the Gulf of Aqaba. The blockade closed Israel's sea lane to East Africa and the Far East, hindering the development of Israel's southern port of Eilat and its hinterland, the Nege. Another important objective of the Israeli war plan was the elimination of the terrorist bases in the Gaza Strip, from which daily fedayeen incursions into Israel made life unbearable for its southern population. And last but not least, the concentration of the Egyptian forces in the Sinai Peninsula, armed with the newly acquired weapons from the Soviet bloc, prepared for an attack on Israel. Here, Ben-Gurion believed, was a time bomb that had to be defused before it was too late. Reaching the Suez Canal did not figure at all in Israel's war objectives.
The escalation continued with the Egyptian blockade of the Straits of Tiran, and Nasser's nationalization of the Suez Canal in July 1956. On October 14, Nasser made clear his intent:"I am not solely fighting against Israel itself. My task is to deliver the Arab world from destruction through Israel's intrigue, which has its roots abroad. Our hatred is very strong. There is no sense in talking about peace with Israel. There is not even the smallest place for negotiations." Less than two weeks later, on October 25, Egypt signed a tripartite agreement with Syria and Jordan placing Nasser in command of all three armies. The continued blockade of the Suez Canal and Gulf of Aqaba to Israeli shipping, combined with the increased fedayeen attacks and the bellicosity of recent Arab statements, prompted Israel, with the backing of Britain and France, to attack Egypt on October 29, 1956.
Gamal Abdel Nasser, who declared in one speech that "Egypt has decided to dispatch her heroes, the disciples of Pharaoh and the sons of Islam and they will cleanse the land of Palestine....There will be no peace on Israel's border because we demand vengeance, and vengeance is Israel's death."...The level of violence against Israelis, soldiers and civilians alike, seemed to be rising inexorably.
(p. 101) To them the murderous fedayeen raids and constant harassment were just another form of Arab warfare against Israel...(p. 102) Israel's aims were to capture the Sinai peninsula in order to open the straits of Tiran to Israeli shipping, and to seize the Gaza strip to end fedayeen attacks.
