Imho, this really has nothing to do with treaty wording and everything to do with holding grudges. All it takes is a little humility from both sides and this will all end.
PC, TPF was your home once and you got your shots in, why not let them off with white peace? Yeah, yeah, we know they try to kill you off every chance they got. But where did you guys came from in the first place? There's nothing left to destroy anyways. Be the bigger man.
TPF, it was pretty clear you guys had it in for PC from the start. With Slayer gone now and no more allies left to defend, I really don't see why you guys can't communicate with PC and re-negotiate the terms. They're a fair bunch for the most part and will prob let you off if shown a little respect. You were comrades once. Why let petty grudges get the best of you?
I don't mean to preach, but why can't we just all get along until we build up, and nuke each other into oblivion in the next great war?
