A better war might have been Cathay versus Zonasa since they both lay claim to Haul - for example.
Two evenly matched realms having their own conflict rather than dogpiling into one which is nothing to do with them and making things ridiculously onesided.
Treaties, they are a wonderful thing. No doubt that war will come, but not when the matter was so recently "resolved". The thing was ridiculously one-sided from the outset, what changed was which side had the numbers.
