US Secretary of State John Foster Dulles was deeply suspicious of Egyptian president Gamal Abdel Nasser, whom he believed to be a reckless and dangerous nationalist. Following Egypt's arms deal with Czechoslovakia, however, others in the Eisenhower administration convinced Dulles that the American aid might pull Nasser back from his relationship with the Soviet Union and prevent the growth of Soviet power in the Middle East. In December 1955, Secretary Dulles announced that the United States, together with Great Britain, was providing nearly $75 million in foreign aid to Egypt to help in the construction of the Aswan Dam on the Nile River. In response to Nasser's increasing attacks on Western colonialism and imperialism and Egypt's continued alliance with the Soviet Union, Britain and the United States withdrew funds for the Aswan Dam in July 1956. That action drove Egypt further toward an alliance with the Soviet Union and was a contributing factor to the Suez Crisis later in 1956. Nasser responded to the aid cut by nationalizing the Suez Canal and the Soviets then rushed to Egypt's aid; the Aswan Dam was officially opened in 1964.
