The Cold War ended without the destructive final global war that had often been envisioned in popular culture, and the public's fears of World War III were allayed. On the other hand, the previously-classified Stanislav Petrov incident of 1983 seemed to imply that the risk of accidental nuclear war because of technical malfunction was greater than had previously been anticipated. The theme of nuclear armageddon launched by military artificial intelligence computer systems without human decision was explored in the 1991 blockbuster movie "". In the early 1990s and the Gulf Crisis, tabloid papers and other press discussed whether World War III would be linked to prophecies of Nostradamus concerning a third great war. A World War III crisis was also featured in the 1992 Canadian movie "Buried on Sunday" in which a separatist island in Nova Scotia threatens to use nuclear missiles from a Russian submarine to strike the US and Canada.
