Suez Crisis: Soviet Threats and US Diplomatic Pressure for Withdrawal (1956)

SUMMARY

The 1956 Suez Crisis unfolded after Egypt nationalized the Suez Canal, prompting a joint attack by Israel, Britain, and France in late October 1956. This action drew strong condemnation and diplomatic intervention from both the United States and the Soviet Union, leading to the withdrawal of the invading forces. During the crisis, the Soviet Union issued threats of military intervention, which are widely discussed in historical analyses.

Declassified US diplomatic records indicate that the US exerted significant diplomatic pressure to secure the withdrawal of its allies. Historical analyses suggest that Soviet threats, while impactful, were often issued after the peak of the crisis had passed, leading some researchers to assess them as bluffs. The interplay between superpower pressure, particularly from the US, and the timing and intent of Soviet threats, remains a key area of analysis regarding the crisis's resolution.

STRONGEST CASE FOR

The strongest argument for Soviet threats significantly influencing US diplomatic pressure is that the US aimed to prevent a broader conflict and avoid appearing aligned with 'imperialist' actions, especially given the ongoing Cold War rivalry. The potential for Soviet intervention, regardless of its ultimate credibility, would have compelled the US to act swiftly and decisively to de-escalate, thus increasing the urgency and intensity of its diplomatic demands for withdrawal from Britain, France, and Israel. The US would not want to risk a direct superpower confrontation or cede moral high ground to the USSR by failing to condemn the invasion.

STRONGEST CASE AGAINST

The strongest counter-argument is that US diplomatic pressure was primarily driven by its own strategic interests, including maintaining influence in the Middle East, opposing colonial actions, and preventing a rift with Arab states, rather than being solely or even primarily a reaction to Soviet threats. Analyses suggest that Soviet threats were often issued retrospectively, after the crisis had peaked, indicating they were more for political posturing than genuine intent to intervene. The US opposition to the invasion was consistent with its decolonization policies, and its economic leverage over Britain and France was a more direct and verifiable tool for securing withdrawal.

    The thing is America did give support for a diplomatic pressure to be put on Nasser, as I said. Besides, the military operation was a virtual success, it was only outside diplomatic and economical factors that lead the British, French and Israelis to withdraw.

    The three countries invaded to try and maintain control over the canal, but international pressure caused them to withdraw. It's cited as the reason/evidence that Britain and France dropped in international significance compared to the US and USSR.

    It's clear the US wanted to increase its own influence in the area, and while there's no guarantee that the Eisenhower Doctrine that came after Suez was conceived of before, the fear of Soviet influence in the Middle East was well-established before the war.
