If that pushes back some of the other dates so be it.
So all of the things that happened still happened in relation to each other, just maybe if Khan left Earth in the early 21st century, maybe the Romulan war happened closer to the end of the 22nd century. Everything just gets pushed back a bit, but the overall story is the same.
Precisely, setting the Eugenics Wars into the 90s in a show that was produced during the 60s translates into "the not too distant future".
The basic idea behind all that "pre-history" of Trek seems to be that humankind might go through hell before things start to improve, a pretty natural idea during the Cold War.
