Given the GTVA's massive advantages in several areas, how did the NTF even manage to hold out for 18 months of war, until the events of FS2?
The NTF had:
-Three systems,
-somewhat-outdated strikecraft and capships,
-incompetent commanders who make stupid tactical decisions due to fanaticism (if Koth can be taken as an example),
-and a supreme leader who didn't even believe in his faction's own cause, and so wasn't actually committed to an NTF victory.
The GTVA, on the other hand, had:
-the rest of the loyalist Terran systems and fleet,
-all of the Vasudan systems and fleet (thanks to the Vasudans' superior economic recovery under Khonsu, it's a reasonable conjecture that the Vasudans had a larger industrial base than all the Terran systems combined, and therefore a larger fleet),
-better military professionalism overall (Command's bad decisions notwithstanding),
-more advanced technology in some areas (though their tech development didn't really pick up until around FS2).
Given all the GTVA's advantages, they would logically have been able to field a much larger and better fleet than the NTF, and therefore quickly quashed the rebellion once they had time to mass their forces. But, as it stands, they were unable to make any major gains during the 18 months between the rebellion's start and FS2. As late as FS2, Koth's offensive in Epsilon Pegasi, if it had succeeded, actually could have made the GTVA sue for peace. The GTVA only finally won when Alpha 1 and the Colossus took the field. Jokes about GTVA Command's incompetence aside, why do you think the war could have lasted so long?
Here are some factors that MIGHT help explain why the war took so long:
-Bosch was playing defense with the NTF fleet while he worked on ETAK and harvested Ancient artifacts, putting together the pieces of his contact-the-Shivans plan. Still, especially given that the NTF was fighting the GTVA in contested systems rather than hunkering down behind node blockades in its core systems, I don't know how much difference that would've made.
-GTVA Command obligingly let the war drag on until Bosch had finished ETAK. They
did let Bosch go during the events of FS2 (which also raises the question of why Command later seemed to abandon whatever their plan was when they just tried to kill Bosch with the Colossus at the Knossos). If true, this theory requires them to have known about Bosch's ETAK research well before FS2.
-Hidden NTF sympathizers in important GTVA positions helped sabotage the GTVA's war effort.
-The GTVA was only fighting the NTF with a portion of their strength, while keeping a large part of their fleet on Shivan watch, like in WiH with the Sol war. By this point, though, you'd figure Command would have said "enough is enough" and just wiped out the NTF with one massive attack, giving how much of a pain the NTF has become.
To be honest, I don't know how much
actually thought this scenario out. They made a detailed setting with FS2, but by this point, us fans have thought more about the logic of their story than they ever did. I don't think FS2 itself provides any explanation for why the war took so long, so unless I missed anything important, any explanation will have to be fanon.
So. Theories? Comments?
