There was a very good made docu by the german ZDF, called WW3, too. Beginning was Glasnost/Gorbi failing, some abusing following, naval conflicts at atlantic and finally a soviet invasion of Germany. After failure of all diplomatics, nukes follow. After 120 minutes of escalation the movie stopps and shows the real history in short flashbacks.
As a child of cold war I was reminded of many many historic facts while viewing that movie.
And I remembered how often we were damned near to make that fiction real.
