I talked about fairness in my previous post and, imho, that's not a good start. Especially knowing both nations situation.
Everybody knows that french have some internal problems which have to resolve, and denying them those ports (which were supposed to be empty) will increase their struggles and disorganization.
On the other hand the swedish have already earned some conquest marks and plenty of PvP marks, they have recieved lots of experienced RvR and PvP players and their organization is pretty good.
So, on paper, it's a 1 vs 1 war, but looking at both nations current situation it's obvious that french are not ready to fight and, if swedish players want to have a decent war they should respect France till their players are prepared for war.
