The Rules for Wars goes as followed:
1. Wars can be suggested by any and everyone.
2. Only Kages, Clan leaders, and Leaders of Criminal Organizations can start wars.
3. Wars cost money.
4. Starting wars require you to build forts, stock up on weapons, food, and medical supplies.
5. Expect lives to be lost and prisoners to be taken.
6. The losers of the war will have to pay the fines for the war if the winner chooses to fine you(ex. lightning country defeats earth country and fines them half a million ryo.). The winner can choose to completely destroy the losing country or village. (Even if the losing force's country or village is destroyed they can still have survivors.)
7. Just because the winners win the war it doesn't mean their forces doesn't suffer damage as well.[/color]
