It has been pointed out by Lorgan before, that the enfasis on number of wars, might be a completely wrong way to look at things, but rather war-activity, and by this is meant, how many battles are made in how much time, and other things which are 'war-ey'.
Having a war on itself is as much having a war as being at peace wiht another nation, if both nations don't really do anything, or if they just battle once every week or two...
later edit:
Furthermore, Tom's stats are more relevant than this poll, for example, the votes are extremely dependant on HOW many characters you have.
Someone with 5 characters with 2 at war vs a newbie with 1 character at war out of 2 characters means that the noob is in more wars than the older player proportionately. The poll doesn't 'mean' anything at alllll. It should be in fractions or % of characters for it to mean anything at all. Right now it's just randomn numbers being voted on with no meaning.
