Why should there be a Russian server? This game operates on "as few servers as needed" basis. Even if the Russians would have a separate server, who would stop them to play on pvp1 like the Americans do?
While there may be arguments that some gameplay mechanics could change, i also think that not all sandboxy solutions have been tried up yet. Basically (and here i speak in a wholly personal capacity) Sweden has three choices: 1. Wait for France and GB to recapture it's ports (which, as Fredrikstedt today has shown to us, might be a long process), 2. succumb to the enemy and basically become a peacefull danish protectorate or 3. ask one of your more populated allies for 4-5 ports in a safe location on the other end of the map to rebuild your strengh.
