You can't even properly defend or parttake in the war to save the Moot. How you going to get to Koshtlom?
Terran is not the 'moot and the 'moot is not Terran. An important partner, sure, but I see no threat to D'Hara or Barca. As for getting to Koshtlom... with the number of armies converging on your realm, that ought to be an easy task.
