1:Allied to OC, well molly's do not like cardamine that is true enough but we share the similar goal and similar enemies so it is logical we are friendly. Outcasts hate Corsairs more then ever so do we since that little bombarding of our planet.
2: Rogues, well Technology off course and Rogues along side with junkers supply our bases with needed comodities, so it is logical we make an alliance.
In Bretonia/Kusari war as Banza stated there we would help Bretonia, our internal disputes would be set aside while we deal with enemy coming from outside and then fight with Bretonia. Ask yourself if Bretonia loose, from who will we get Dublin. Im sure Kusarians would kill everyone on their way to achieve their goals.
Please don't mention IRA since it doesn't have anything with this game nor Molly's. Maybe it reminds you of something but it is not. And how corsairs fight from us all, well ask them, as long as we don't see them they will stay alive. And Molly's are not alike xenos, what we want to have is dublin and free rights to exploit our gold mines which that "old hag queen" won't allow us since they are valuable. We Attack military targets and tax traders since diplomatic channel is dead and through it we couldn't get what we wanted. There is two opinion on this always Bretonia and Molly so im sure someone will disagree. Thank you
