After the conclusion of the 1956 Sinai Campaign, Israel entered a significant period of strategic calm along its southern frontier with Egypt. This decade, lasting until the escalation of May 1967, represents one of the most stable intervals in the early history of the Arab-Israeli conflict. The cessation of hostilities allowed for the rapid development of Israel's southern regions and the stabilization of its fledgling national economy. This era of relative quiet was the direct result of the military achievements during Operation Kadesh and the subsequent diplomatic arrangements brokered by the international community.
Historical Background and the 1957 Withdrawal
The 1956 conflict was originally triggered by Egypt's nationalization of the Suez Canal and its illegal blockade of Israeli shipping through the Straits of Tiran. Israel's swift victory in the Sinai Peninsula demonstrated a qualitative military edge that forced a major reconsideration of Egyptian tactical aggression. Under significant international pressure, particularly from the Eisenhower administration in the United States, Israel agreed to withdraw from the captured territories in early 1957. However, this withdrawal was strictly contingent upon specific security guarantees and the deployment of international observers to prevent future escalations.
A critical component of this post-war arrangement was the stationing of the first United Nations Emergency Force (UNEF) along the border and at the strategic point of Sharm el-Sheikh. This international presence served as a vital buffer, preventing the immediate resumption of the low-level guerrilla warfare that had plagued the previous years. For Egypt, the presence of UNEF provided a face-saving mechanism to avoid direct confrontation while its military was being rebuilt. For Israel, it ensured that the Sinai would remain largely demilitarized and that the southern approach to Eilat would remain unthreatened.
Key Facts of the Quiet Decade
- The complete cessation of Egyptian-sponsored Fedayeen terror raids from the Gaza Strip and Sinai.
- The establishment of the Port of Eilat as a major international trade hub following the lifting of the maritime blockade.
- The deployment of the United Nations Emergency Force (UNEF) as the first peacekeeping mission of its kind.
- A ten-year period of massive civilian infrastructure growth in the Negev Desert and southern Arava region.
- The formalization of "red lines" regarding Israeli maritime sovereignty in the Red Sea.
Analysis of Deterrence and Security
The cessation of the Fedayeen raids was perhaps the most immediate benefit for Israeli civilians living in the Negev panhandle. Prior to the 1956 campaign, Egyptian-sponsored infiltrators routinely attacked Israeli agricultural communities and essential water infrastructure, leading to significant casualties. The deterrent effect of the IDF’s performance during Operation Kadesh made it clear to the Egyptian leadership that such provocations would meet with overwhelming force. Consequently, the border remained largely silent, facilitating the successful growth of new towns like Beersheba and the industrial center of Dimona.
During this stable period, Israel also secured its maritime rights, ensuring that the Port of Eilat could function as a vital gateway to Asia and Africa. The opening of the Straits of Tiran ended a years-long blockade that had stifled Israel's trade potential and threatened its energy supplies. This maritime freedom was viewed by the Israeli government as a sovereign necessity for national survival and a non-negotiable status quo. According to documentation from the Jewish Virtual Library, the commitment to keeping these waterways open became a cornerstone of Israeli security doctrine during these years.
Strategic deterrence was further bolstered by Israel’s procurement of advanced French weaponry, including the Mystère and Mirage fighter jets, during the late 1950s. The Israel Defense Forces utilized these ten years of quiet to transform the Air Force into a world-class strike component and to professionalize its armored corps. This period of quiet was not a passive peace but rather an active interval of intense nation-building and military consolidation. Detailed records at the Israel State Archives show the intense diplomatic efforts required to maintain this fragile but essential status quo.
Conclusion and Lasting Significance
The quiet decade finally collapsed in May 1967 when President Gamal Abdel Nasser demanded the withdrawal of UNEF and closed the Straits of Tiran once again. While the period ended in the Six-Day War, the ten years of deterrence had allowed the State of Israel to mature both as a sovereign society and a military power. This era proved that firm military action, when backed by clear strategic objectives, could yield prolonged periods of regional stability. The lessons of post-1956 deterrence remain highly relevant in contemporary Israeli security discourse regarding border management and the effectiveness of international guarantees.
