My two cents
On Quarantine - it may work in real life and it may be legal even here, but this time it is quarantine that disallows free usage of Lodamun - Dolgava sea strait. So trade vessels can only either more around Keris to North Pole or move around Seleya or go through quarantine which is very time consuming.
So nations are free to try to negotiate free passage of their trade ships (btw MrYankees, I noticed in your last post that there is an option to make a sort of tunnel that trade ships may use to pass the Quarantine zone without being checked, so that is taken into account) and if that does not happen use it as a ground for war declaration.
edit: I still like the idea ooc, despite I will fight it very much IC
On Military - maybe it is worth to create a role model for military might of average (standard) Terran nation. So if nation has average number of population, average GDP, is military oriented (Terran role model is ) then what is national military might. Then you can see, ok my nation is military oriented but twice more population than average, so it is far to assume I have twice military.
It would be of good help especially for players like me who do not know anything on aircraft carriers, etc.. (I mean I RP President here not the General ), so I can say what are military forces of my nation based on average example.
