In May 1967, the State of Israel faced an existential threat as Egypt, Syria, and Jordan mobilized their forces along its borders. Following Egyptian President Gamal Abdel Nasser's decision to expel United Nations Emergency Forces and block the Straits of Tiran, Israel entered a period of intense uncertainty known as the "Waiting Period" or Hamtana. This three-week interval was characterized by a full-scale mobilization of the Israel Defense Forces and a desperate search for a diplomatic solution. The nation’s survival hung in the balance as the international community remained largely passive in the face of escalating Arab aggression.
Historical Context and Regional Provocations
The crisis began on May 15, 1967, when Egyptian forces moved into the Sinai Peninsula in a direct violation of previous international understandings. This move was quickly followed by the removal of UN peacekeepers who had served as a vital buffer since the 1956 Suez Crisis. By closing the Straits of Tiran to Israeli shipping, Egypt committed an act of war under international law, effectively strangling Israel's southern maritime lifeline. These provocations were met with bellicose rhetoric from Cairo, where Nasser openly declared his intent to achieve the total destruction of the Jewish state.
Key Facts of the 1967 Mobilization
- The 'Waiting Period' lasted from May 15 until the outbreak of war on June 5, 1967.
- Israel mobilized over 250,000 reservists, representing a significant portion of its adult male population.
- The Straits of Tiran closure blocked all oil imports from Iran, threatening Israel's energy security.
- A National Unity Government was formed on June 1, bringing Moshe Dayan into the Ministry of Defense.
- Foreign Minister Abba Eban traveled to Paris, London, and Washington to secure international intervention.
The Strategic Burden of the Waiting Period
The 'Waiting Period' was a time of immense psychological pressure for both the Israeli public and its political leadership. Prime Minister Levi Eshkol initially pursued a cautious path, hoping that American or British naval intervention would reopen the straits and de-escalate the conflict. While Eshkol sought a diplomatic breakthrough, the Israeli economy effectively shut down as nearly all able-bodied men were drafted into emergency military service. In the cities, civilians prepared for the worst, with many fearfully anticipating a catastrophic regional war if the combined Arab armies succeeded in their invasion.
Israel’s military strategy relied heavily on its unique reserve system, which allowed for a rapid transition from a small standing army to a massive fighting force. During the mobilization, the IDF successfully called up hundreds of thousands of reservists, positioning them strategically to face threats on three separate fronts. This logistical feat was accomplished despite the severe strain it placed on the country's social and financial infrastructure. Soldiers waited in the desert heat for weeks, their presence serving as a defensive shield while the cabinet debated the timing of a necessary preemptive action.
Strategic Analysis and Diplomatic Failure
The decision to wait, though controversial at the time, was a calculated strategic move designed to secure international legitimacy for any future military action. By exhausting all diplomatic avenues, Israel demonstrated to the world that it was the aggrieved party acting strictly in self-defense. However, the delay also allowed the Arab coalition to further consolidate their positions and coordinate their complex battle plans. Historians often debate whether the waiting period was a sign of political hesitation or a masterclass in diplomatic maneuvering that ultimately paved the way for victory. According to records at the Jewish Virtual Library, the internal tension nearly led to a political collapse before the formation of the unity government.
The psychological dimension of the waiting period cannot be overstated, as the Israeli citizenry lived through three weeks of agonizing dread and preparation. Media reports from the era capture a nation in limbo, with the "Voice of Israel" radio broadcasts becoming the primary source of both information and collective anxiety. This period forced the Israeli leadership to confront the limits of international guarantees, specifically the 1957 assurances regarding the freedom of navigation through the Red Sea. The failure of the maritime powers to organize a "Regatta" to challenge the blockade proved to Israel that it could only rely on its own strength for survival.
Conclusion and Historical Significance
The impasse finally broke on June 1, 1967, with the formation of a National Unity Government and the appointment of Moshe Dayan as Minister of Defense. This shift in leadership signaled a move away from diplomatic patience toward a policy of active military intervention to remove the existential threat. The subsequent execution of Operation Focus on June 5 remains a defining moment in modern military history and tactical aviation. Ultimately, the waiting period solidified Israeli national resolve and ensured that when the IDF finally struck, it did so with the full weight of a unified nation.
