The first phase of the Cold War began shortly after the end of the Second World War in 1945. The United States created the NATO military alliance in 1949 in the apprehension of a Soviet attack and termed their global policy against Soviet influence "containment". The Soviet Union formed the Warsaw Pact in 1955 in response to NATO. Major crises of this phase included the 1948–49 Berlin Blockade, the 1927–1949 Chinese Civil War, the 1950–1953 Korean War, the 1956 Hungarian Revolution, the 1956 Suez Crisis, the Berlin Crisis of 1961 and the 1962 Cuban Missile Crisis. The US and the USSR competed for influence in Latin America, the Middle East, and the decolonizing states of Africa and Asia.
