In his review of Dark War Revelation, the Sci-Fi/Fantasy Reviewer remarked “(it’s always 1985 in these books for some reason)”. So, why is it always 1985?
One possible reason is (even subconciously) imitating Hackett’s original The Third World War: August 1985. Another,as argued by the WW3 1987 blog is that 1985 is the most “fair” of the time periods. Still another may just be that it’s the middle of the decade, so it’s an easy number to reach.
But yes, 1980s WWIII stories often appear in 1985.
