Ok, some points I'd like to add to the discussion that I came across.
1. The EA-GTVA war should be a 2-front war. Several CBs indicate clearly that Delta Serpentis is entirely under EA control, same for Ross 128. Unless the Nodemap has been changed significantly, half a dozen systems have been cut off from GTVA. FS2 canon says they're densely populated and industrialized. EA could try to seize these systems (though Beta Aquilae is of course a more valueble target), or GTVA could open a second front, but neither happens. No GTVA units enter EA-controlled Ross 128 despite being only weakly-defended.
2. Despite being a "strategic important asset" to GTVA and EA having control over Delta Serpentis for quite a while, Aeneas station managed to avoid capture/destruction for a long time. Even though asteroids might make things more complicated, something probably doesn't justify delays of more than a week or so, and the force EA ultimatly send consisted only of 2 corvettes, a cruiser and a few wings - nothing EA wouldn't have been able to delpoy weeks or months ago if it mattered to them at any point.
3. This here: https://www.hard-light.net/forums/index.php?topic=94956.msg1871517#msg1871517
It's only about the ending of part 1; it doesn't spoil anything you couldn't deduce from part 1/tech descriptions.
