I'm not sulking, I don't think warring is evil, I think one-sided (technically unprovoked) warring is evil.
Next set I won't have more defences, and neither will anyone else, unless they decide to war you/EURO back for this set. It has to be the leaders who instigate the change, once they start enforcing their own members to have defence then change will happen. Maybe your holy warring set after set will do that, but has it worked so far?
I know nothing I've written will change your mind, but maybe it'll make you think about possible different courses of actions. You may have already tried these but as I haven't been around recently I don't know, but for me the threat of war will create much better tension than the feeling of "oh we've been shafted by a FS... again"
