When I led GRN we had a cease fire with the Mollys, and I believe even a trade pact. This was years ago but it did solidify our flank through Dublin at first. I don't know what became if that.
Honestly the BAF should reach out to the Mollys and accept the help of the unlawful parties of Bretonia, and especially the Omega Triumvirate. That's a decent fleet right there that can strike Gallia from the side. Legitimizing the Mollys as a lawful entity eith Dublin and establishing formal relations at this point at least can keep the GRN from storming the system with a massive fighter and gunboat swarm unopposed.
That's just how I view things honestly. Bretonia is nearly finish if Gallia deploys any more of its fleet and finds a way to clear asteroids. Or if Gallia repairs/replaces the current jump gate.
What confuses me is why isn't Gallia sending a fleet into Kusari to crush the Exiles and then hit Liberty through Kepler and Galileo. It has the raw numbers for such a move...but hey, there's probably reasons I don't see.
