The following outline is provided as an overview of and topical guide to the Cold War:
Cold War – period of political and military tension that occurred after World War II between powers in the Western Bloc (the United States, its NATO allies and others) and powers in the Eastern Bloc (the Soviet Union and its allies in the Warsaw Pact). Historians have not fully agreed on the dates, but 1947–1991 is common. It was termed as "cold" because there was no large-scale fighting directly between the two sides. Based on the principle of mutually assured destruction, both sides developed nuclear weapons to deter the other side from attacking. So they competed against each other via espionage, propaganda, and by supporting major regional wars, known as proxy wars, in Korea, Vietnam, and Afghanistan.
