The purpose of the Gallia-Bretonia war is that the Gauls must conquer or destroy planet New London. Now, it is clear that Bretonia will lose the war. If Bretonia looses, that would open the path from Gallia to Liberty. Gallia has already threaten Liberty to invade them. If Bretonia and Liberty lose the war, the biggest part of Sirius would be controlled by Gallia, what Rheinland and all of Sirius don't want. I think the 3 Houses should unite against Gallia and Kusari and bring total war to Sirius. While the authorities are busy fighting, pirates will spread terror amongst the less guarded systems. Total war. Everybody will be able to shoot something whenever he/she wants, everibody will be content. Bretonia will defend, Liberty will send its ships trough Magellan and Rheinland will keep Kusari busy in and trough Sigma 13. Liberty and Bretonia also have close borders with Kusari, but Rheinland doesn't have the path to Gallia, so they can concentrate their forces on Kusari. There are some things that are against this story, like Rheinlands trading relations with Kusari and the war against Liberty.
I think that the houses are not blind and can see the Gallia treat. I'm a Bretonia lover, so I don't realy like to see Bretonia fall and I think that the great House unification would have to happen before Bretonia falls.
After Gallia isn't considered as a dangerous enemy and Kusari sees that they will lose and shift to the Sirius side, after promised benefits (somewhat like Italy in the 1st WW shifted to the side of the of the Allies), everything returns to the old status (maybe in 4.88, if they make it). Liberty attacks Rheinland again, Kusari gets some of the promised benefits, they unite with Bretonia and continue the war vs. Gallia. They sometimes win, sometimes lose, standard Tau war, etc... So, ladies and gentlemen, what do you think about this? I must mention that I'm a Bretonia lover, so I don't like to see them falling. There are also some Gallia lovers, who don't like to see the mighty Gallia falling. Everybody can comment about this, add something, remove something, or agree that the Fletcher's version is better. So, what do you say?
