The Sinai Campaign of 1956, known in Israel as Operation Kadesh, represented a pivotal moment in the leadership of Prime Minister David Ben-Gurion. Faced with a tightening Egyptian blockade of the Straits of Tiran and the increasing frequency of fedayeen terror raids originating from the Gaza Strip, Ben-Gurion recognized an existential necessity for military action. This period was characterized by a complex intersection of military strategy and clandestine diplomacy as Israel sought to break its regional isolation. Ben-Gurion’s primary objective was not merely territorial expansion but the establishment of a sustainable security environment for the young Jewish state.
The leadership role assumed by Ben-Gurion during this crisis demonstrated his unique ability to balance immediate military imperatives with long-term geopolitical realities. He understood that Israel could not act alone against the regional weight of Egypt, particularly following the 1955 Czech-Egyptian arms deal that threatened to tilt the balance of power toward Cairo. Consequently, he orchestrated a secret alliance with France and Great Britain, culminating in the Protocol of Sèvres. This high-stakes diplomatic maneuver aimed to align Israel’s security needs with the colonial interests of the European powers regarding the Suez Canal.
Background and the Path to Conflict
In the years leading up to 1956, the security situation for Israel had deteriorated significantly due to the aggressive policies of Egyptian President Gamal Abdel Nasser. The Egyptian blockade of the Straits of Tiran effectively cut off Israel’s only maritime exit to the Red Sea and the Indian Ocean, strangling the port of Eilat. Simultaneously, the Suez Canal remained closed to Israeli shipping in direct violation of international law and previous UN resolutions. These actions, combined with the escalating threat from the fedayeen, convinced Ben-Gurion that a preemptive strike was the only way to prevent a coordinated Arab invasion.
The strategic environment was further complicated by the Cold War dynamics and the shifting stance of the United States under President Dwight D. Eisenhower. While Ben-Gurion sought to secure Israel’s borders, he had to navigate the risk of alienating the world’s rising superpower. He meticulously prepared the Israel Defense Forces (IDF) for a rapid campaign while maintaining a facade of domestic normalcy. This dual-track approach of military readiness and diplomatic secrecy allowed Israel to achieve a stunning tactical victory in the Sinai within just one hundred hours of combat.
Key Facts of the Sinai Campaign
- The Sèvres Protocol established a secret tripartite agreement between Israel, France, and Britain to reclaim the Suez Canal and neutralize the Egyptian military threat.
- Operation Kadesh resulted in the swift capture of the entire Sinai Peninsula and the Gaza Strip by Israeli forces between October 29 and November 5, 1956.
- Heavy diplomatic pressure from both the United States and the Soviet Union forced a cessation of hostilities and eventually led to the withdrawal of all foreign troops.
- The conflict led to the deployment of the United Nations Emergency Force (UNEF), the first of its kind, to act as a buffer in the Sinai and Gaza.
- Israel’s withdrawal was conditioned on international "security guarantees" regarding the freedom of navigation through the Straits of Tiran.
Diplomatic Struggles and Security Guarantees
The most grueling aspect of the 1956 crisis for Ben-Gurion began after the military victory, as the international community demanded an unconditional Israeli withdrawal. President Eisenhower sent several stern letters to Ben-Gurion, threatening economic sanctions and a complete break in diplomatic relations if Israel did not vacate the Sinai. Ben-Gurion initially resisted, famously declaring in the Knesset that Israel had established the "Third Commonwealth." However, he soon realized that holding territory without international legitimacy would be a strategic catastrophe that could bankrupt the nation and leave it vulnerable.
The ensuing diplomatic struggle focused on obtaining concrete guarantees that the pre-war status quo would not return. Ben-Gurion and Foreign Minister Golda Meir engaged in intense negotiations with the United States to ensure that the Straits of Tiran would remain an international waterway. According to the Israel Ministry of Foreign Affairs, the final agreement involved a memorandum from the U.S. government acknowledging Israel’s right to self-defense if the blockade were ever reinstated. This diplomatic compromise allowed Ben-Gurion to withdraw his troops while claiming a strategic victory for Israel's maritime rights.
Ben-Gurion’s decision-making process was guided by the realization that military strength must be supplemented by political alliances. He prioritized the stationing of UN forces at Sharm el-Sheikh to prevent the Egyptian army from re-imposing the blockade. Although these guarantees were eventually tested and failed in 1967, they provided Israel with a decade of relative quiet and rapid economic development. The Sinai-Suez Campaign remains a study in how a small state can leverage military success into diplomatic leverage under the shadow of global superpowers.
Conclusion and Historical Significance
The 1956 Sinai Campaign solidified David Ben-Gurion’s legacy as a pragmatist who placed the survival of the state above ideological purity or territorial expansion. By agreeing to withdraw in exchange for security guarantees, he successfully transitioned Israel from a pariah state to a recognized regional power with a legitimate claim to international maritime access. This period also marked the beginning of a fundamental shift in Israeli foreign policy toward a deeper strategic reliance on the United States. The lessons of 1956 continue to inform Israel’s doctrine regarding the necessity of maintaining "defensible borders" and the importance of international legitimacy.
Ultimately, the diplomatic struggle of 1956 proved that military might is most effective when it serves a clear and achievable political end. For Ben-Gurion, the Sinai was a means to an end: the opening of the gates of the world to Israeli commerce and the temporary cessation of cross-border terrorism. The crisis underscored the reality that for Israel, security is not just found in the lines on a map, but in the strength of its alliances and the clarity of its international standing. This nuanced approach to leadership ensured that the Sinai Campaign, despite the withdrawal, remains a landmark achievement in the history of the State of Israel.
