Of course, but whats the point of the deal? Sure I can talk to someone and suggest it'd be better for both of us to expand against indies than fight each other, or join together to attack a 3rd party, but if it's fine to break a deal at any time, why actually put terms on it?
More specifically, what's the point in the usual NAP with 3 turns of warning? If there are not even any diplomatic consequences, since that's the point of this game variant, why would I ever give 3 turns of warning instead of a surprise attack?
