You realize that preparing for that future war is going to be the New Monarchy's dependence, right? What's the point in building something and deciding not to defend it? New Monarchy wants to build. Future War Cult wants to survive. Kinda goes hand in hand. The difference is that Future War Cult wants to invest in war machines and combative capability while New Monarchy wants to rule a society for the sake of having a ruler. Which... to be honest, the last time that happened things didn't go to well... Dead Orbit just wants to run away like idiots. We can see how well that worked for the Traveler...
