Queen's WWIII speech, scripted but never given, was prepared when tension between the USSR and the US rose to the point that nuclear war seemed likely.
Relations between the Soviet Union and the West had become so tense 30 years ago that British officials drew up a speech for Queen Elizabeth to deliver to the nation in the event of a nuclear WWIII, newly released archives showed on Thursday.
In the speech, the monarch was to urge Britons to remain united and resolute in the face of the "madness of war."
Written by government officials, the hypothetical speech was part of a secret exercise designed to prepare Britain for the threat of a possible World War Three, but was never broadcast.
It starts by referring to the queen's traditional Christmas address to the nation.
