Liberty would win. Although Gallia is stronger in the immediate sense, attrition combined with the fact that they have to fight both Sirius and the Council with help Liberty, which can defeat pretty much anyone anyway. Besides, Bretonia and Kusari stand in the way, too weak to pose a threat to liberty, and too strong for Gallia to conquer quick enough. Meanwhile, Liberty can wipe out Rheinland. As for the Nomads, an eventual Nomad-Liberty war would make the latter the victor.
