Cold War

The Cold War was a term used to denote the tensions between the Capitalist nations of the world (particularly the United States and the United Kingdom) and the Communist nations of the world (particularly the Soviet Union) in which, though the tensions were high, no actual fighting occurred. The east and west were, according to the Eleventh Doctor, "standing on the brink of nuclear oblivion." Both sides could easily have destroyed the other. (TV: Cold War)

Behind the scenes

 * Both Invasion of the Dinosaurs and Robot imply that the Cold War was already over at the time those stories took place. However, in the novel Goth Opera, by Paul Cornell, it is noted by Tegan Jovanka, who comes from the year 1981, that the Cold War had ended by 1993.
