The document summarizes events at the end of World War 2 and Britain's declining global power in the following decades. After the war, the Allied powers of Britain, the US, France and the Soviet Union created the United Nations but their alliance broke down, dividing Europe between Western capitalist states led by the US and Eastern communist states led by the Soviet Union. Britain made technological advances but lost military and political authority, such as when the US forced it to withdraw troops during the 1956 Suez Canal crisis.
