If a clan violates the norms of the server then the victim can either get their allies to attack them, can ask for their police to intervene, or can get revenge in the next reset. I think it would be great if clans performed ingame actions that offended other clans which led to wars.

Let me explain it another way. It appears that there were effectively zero real wars this reset. Adding UNAPs to the game will by definition restrict player to player interaction. Is there some other way to balance that out?
