D. United States and Soviet Union ~ The Cold War was the increased political and economical tensions between the United States and Soviet Union post WWII.
Cold War is the designation attributed to the historical period of strategic disputes and indirect conflicts between the United States and the Soviet Union, comprising the period between the end of World War II (1945) and the extinction of the Soviet Union (1991), a conflict of political, military, technological, economic, social and ideological order between the two nations and their zones of influence. It is called "cold" because there was no direct war between the two superpowers, given the unfeasibility of victory in a nuclear battle. The arms race for building a large arsenal of nuclear weapons was the central goal during the first half of the Cold War, stabilizing itself from the 1960s until the 1970s and being revived in the 1980s with the design of the President of the United States Ronald Reagan called "Star Wars".
