During the 1956 Suez Crisis, the Soviet Union sided with Egypt. The USSR viewed the nationalization of the Suez Canal as important to the removal of Western influence from within the Middle East. Additionally, the Soviet Union was willing to fund Egypt because in return, it received access to warm-water ports, which it desperately needed to spread its influence. Though US President Dwight D. Eisenhower was also infuriated at the invasion and had successfully brought an end to end to Suez Crisis by pressuring the invading forces to withdraw from Egypt by early 1957, the United States continued to maintain good relations with Britain, France and Israel and sought to limit Soviet ally Nasser's influence, thus damaging its relations with the Middle East for the next 35 years. By continuing to side with Egypt, the Soviet Union gained more prestige in the Middle East and succeeded in intimidating its superpower opponent, the United States. Nasser's pan-Arab influence spread throughout the Middle East and he soon gained a popular image among those who resented Western colonialism. In spite of his alliance with the Soviet Union, Nasser would not sign a military alliance pact with the nation; made efforts to prevent the spread of Communism and other foreign influences throughout the Arab region by forming a civil union with Syria known as the United Arab Republic (UAR)—a nation which he had hoped other Arab states would eventually join as well—in 1958; and was a founding father of the Non-Aligned Movement in 1961; though the union with Syria collapsed in 1961, Egypt would still be officially known as the United Arab Republic for a while longer.
