Dude, open pew everybody knows about is not a cold war, pretend inRP that it is and my character will laugh at the face of yours like at a fool.
Coming here with a crappy idea and telling me to figure it out how it could work and then blaming the decline of the server on my negativity (while I've just told you why your idea won't work) is not the best way to improve roleplay and gameplay. If you propose an idea, why don't you think about how it could work yourself? Come back with an actual, ironed out concept which has more basis to it than "let's pretend there is no war while we get actual reports daily about our soldiers shooting eachother", and we can talk.
The concepts of either Gallia smashing on the doors of Liberty while Rheinland deals with it's own pirates and rebuilds or Rheinland asking for Gallic help to rebuild the gates, or even Liberty and Rheinland agreeing on a ceasefire has more merit to themselves than your half-baked idea. But of course if you still want to share us the other half of it, and tell how you imagined it being a cold war while actually looking like a cold war too, I'm all ears.
Actually, I'm curious where the talks between Gallia and Rheinland are at the moment.
