Yep! Thanks for the compliments. Rest assured, the NTF isn't going to pull a PI and appear with a new superdestroyer that has them obliterating the GTVA (no offense, CP.) Alikchi, BlackWolf, Adwight and I have all dug into the specific military and diplomatic actions that shifted the balance of power in the war and the linchpins that they rest on. The plot outline we have flips those linchpins and explores the results. There are a couple pivotal missions that could have spelled disaster if they had gone the other way (Endgame, Slaying Ravana) so it's not totally implausible that the GTVA recognizes NTF authority in Polaris/Regulus/Sirius. They won't conquer the galaxy, though; that was never Bosch's objective.
Still, I like your thinking.
