The Egyptian-Czechoslovak arms deal was an agreement between the USSR and Egypt led by Gamal Abdel Nasser, announced in September 1955, to supply Egypt with more than $250 million worth of modern Soviet weaponry, through Czechoslovakia. The deal was a major turning point in the Cold War and greatly impacted the Arab–Israeli conflict.
Instead of siding with either super-power, Nasser took the role of the spoiler and tried to play off the super-powers in order to have them compete with each other in attempts to buy his friendship. Nasser's first choice for buying weapons was the United States, but his frequent anti-Israeli speeches and his sponsorship for the fedayeen who were making raids into Israel had made it difficult for the Eisenhower administration to get the approval of Congress to sell weapons to Egypt. American public opinion was deeply hostile towards selling arms to Egypt that might be used against Israel, and moreover Eisenhower feared starting a Middle Eastern arms race. Eisenhower very much valued the Tripartite Declaration as a way of keeping peace in the Near East. In 1950, in order to limit the extent that the Arabs and the Israelis could engage in an arms race, the three nations which dominated the arms trade in the non-Communist world, namely the United States, the United Kingdom and France had signed the Tripartite Declaration, where they had committed themselves to limiting how many arms they could sell in the Near East, and also to ensuring that any arms sales to one side was matched by arms sales of equal quantity and quality to the other. Eisenhower viewed the Tripartite Declaration, which sharply restricted how many arms Egypt could buy in the West, as one of the key elements in keeping the peace between Israel and the Arabs, and believed that settling off an arms race would inevitably lead to a new war.
The Egyptians made continuous attempts to purchase heavy arms from Czechoslovakia years before the 1955 deal.
Nasser had let it be known in 1954–55 that he was considering buying weapons from the Soviet Union as a way of pressuring the Americans into selling him arms he desired. Nasser's hope was that faced with the prospect of Egypt buying Soviet weapons, and thus coming under Soviet influence, the Eisenhower administration would be forced to sell Egypt the weapons he wanted.Khrushchev who very much wanted to win the Soviet Union influence in the Middle East, was more than ready to arm Egypt if the Americans proved unwilling. During secret talks with the Soviets in 1955, Nasser's demands for weapons were more than amply satisfied as the Soviet Union had not signed the Tripartite Declaration. The news in September 1955 of the Egyptian purchase of a huge quantity of Soviet arms via Czechoslovakia was greeted with shock and rage in the West, where this was seen as major increase in Soviet influence in the Near East. In Britain, the increase of Soviet influence in the Near East was seen as an ominous development that threatened to put an end to British influence in the oil-rich region.
