That and, to be honest, Arcachon fights a very face-paced war with high stakes and Ohnar West is not a nation that likes to gamble so there's really no fear of chaotic attacks.
Ciann is insane by any modern definition but half of her ideas come from essentially nowhere ("There is a raven on that pole, we are meant to invade this land"), which actually makes her rather unpredictable, though I suspect it's going to wear thin on the Holy Legate really quick.
Cathay can't defend itself so it's just worried about picking the wrong side. It hasn't fought a competent war in ages and if Ohnar West capitulates it would find itself absolutely screwed.
