Well, Hireshmont just called Brance a panicky liar unable to manage his own realm in front of the rulers of several realms.
Poke?
I know Astroism can beat the Moot in a war. Hireshmont generally knows that (though if Aurvandil and Madina would lay off it and come help, and if the Lurias would stay out, we'd have a real chance). But Hireshmont and Brance have pushed each other into very uncomfortable positions.
