hmryeah. It's like asking Xenos to go across kusari border. They wouldn't. They are a small organisation bent on killing anything not libertonian. Within Liberty and its borders.
I see FA as the same...
So unless FA is so large (which I can't be certain since synth food does seems popular to Kusari, especially youth), why would they strike in Bretonia with such ambitious plans?
It would be extending the influence and power of a relatively small vanilla faction to the extent of a pirate faction of, I'd say, Hessian caliber.
