AWIY's blacklist of dishonest peoples

[Sombre]

I partly agree with Baalz, but I don't think treaties are worthless simply because they are sometimes broken and I don't think it's worth attacking someone based on the idea that since there's no possibility of a NAP they should be your #1 target. If they haven't made a threatening move towards you (they lack a huge army hovering on the border) and they say they don't have any intention of attacking you and on top of that you have other 'friendly' diplomatic relations such as trade, sharing of information or dividing of indy provinces to avoid conflict, then you haven't got much cause to believe they're going to attack you. Perhaps it's a cunning ploy on their part and they're hiding troops, but that sounds like a legitimate strat they're using, so fair play to them. I know I'd be less trusting of glamoured or stealthy nations and be sure to keep a reserve ready to deal with them.

Of course it would be silly to assume they'll never attack you, or they'll announce it before doing so, unless it's been clearly stated that you have a NAP and it cannot be broken, with the punishment being that they'll be kicked, or you'll refuse to play with them ever again.

I think there's plenty of room for meaningful diplomacy where treaties are still broken. You can also add house rules on top if you'd like.
