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.

History
In 1903, after receiving a wealth of information from the future, Grigori Rasputin foresaw the Cold War. (AUDIO: The Wanderer)

The Doctor took part in some events of the Cold War. The Eighth Doctor was blackmailed by Kim Philby into assisting him against the Players in 1951, whilst his seventh incarnation held Majestic clearance with the United States in 1957. (PROSE: First Frontier, PROSE: Endgame)

The Tenth Doctor made reference to the Cold War during a visit to New Mexico in 1958. (TV: Dreamland)

In October 1963, Susan Foreman read a newspaper with an article on the Cold War. (AUDIO: Hunters of Earth)

In November of that year, a group of Russian spies including Miles Barrington Smythe, aided by MI6 double agent Barker, operated in London. (TV: The Cambridge Spy)

The Cold War had ended by 1993. (PROSE: Goth Opera) However, there were two unnamed power blocs poised to annihilate each other again by 2084. (TV: Warriors of the Deep)

Projects and plans
During the Cold War, there were plans to build an underground headquarters for the British government in the event of a nuclear war. (TV: Invasion of the Dinosaurs)

At one point, to avoid warring, America, China and Russia gave their nuclear destructor codes to Great Britain. (TV: Robot)

The Golgotha Project was formed during the war. (PROSE: Heart of TARDIS)

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 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.
