Are there games in this genre that aren't historical?
A couple of the ones on that list are what might be called "alternate history" e.g. one is a "cold war goes hot" WW3 scenario.
There are plenty of abstract or futuristic war games, so I'm sure someone has done an operational one, but generally this kind of game appeals to someone who wants to play through a detailed simulation, and that's a lot less interesting (and harder to get right!) if you're trying to simulate an original fictional war environment. (I guess simulating the likes of Star Wars might appeal, but then you get into the issue of whether what's seen in the movies can be made to correspond to any kind of logistically grounded simulation at all)
