Its BattleMaster! Why do we have realms threatening others with war if they get into war?! 
Case in point is Cathay, which has declared that it will attack either Arcaea or Greater Aenilia if either one goes to war with the other. If Cathay nobles wants to get bored training in their capital, so be it, but dont keep other realms from going to war.
I say Arcaea and Greater Aenilia should group together and destroy Cathay, and let us in Arcachon battle those Ohnarians alone. 
Cathay and Kindara. Kindara's actually worse, I think, as at least Cathay was doing it between two allies, while Kindara does it for any realms.
And, yeah, you're not getting out of this war that easily
