Why do you think that Gallia have lack of resources after all? They controling some Taus full of it, they have a puppet regime in Kusari. I believe it is more than enough to covering the fleet maintenance. As well as I do not believe that BAF in good condition and position for the offensive kind of war. Bretonian economy must be as good as BAF for now. Liberty at the same time /still/ have a Rheinland as the threat at the backyard so I don't think that Liberty will go too far.
If we talking about the population, it is a 'transatlantic' kind of war for the Liberty so libertorians will not go for full mobilization like Bretonia or Gallia for example.
