Re: Are "Watchmen" & "Back to the Future II" in the same Alternate 198
No, Watchmen has Vietnam concluding roughly a week after Nixon is first elected.
In the alt-1985 from BTTF II, there is a newspaper headline that reads something like "Nixon To Seek 5th Term...Vows To End Vietnam War By 1985". I suppose he could have succeeded... So maybe it is possible that the film's alt-1985 is the Watchmen 'verse. That would make Biff Tannen personally responsible for all that destruction.
