Law II:
I think the requirements in 3.1 are way to low, I'd say at least 2/3 of the vote and proof of some kind of provocation. Also requiring the chieftain to propose a declaration of war shouldn't be required in my opinion, in the rare case war is justified it might be important to act fast, a chieftain that is offline for a few days might delay it even more than the required 3 days for voting.
A way I would find even better would be to not have any way of declaring war but instead a list of things we'd consider acts of war (like grieving, harbouring grievers or thieves and such) and if any of those would happen we would consider the other side to have declared war on us.
Minor criticism:
Treasury report and such seem important enough to publish more often than every 2 or 3 months (I'd prefer more like every 2 weeks or monthly).
As it is, mostly due to the low requirements of declaring war, I vote against law II ("nay").
