Because of the repeated betrayal and lies if we had peace we would surely not trust you at all and make sure we had all Carelian forces nearby for quite some time before we even thought about helping our allies with their war I am rather sure.
It was spun pretty well within Suville; most of the country was fed up with Carelia by the time we broke alliance, especially since Suville lost a hero in the most recent expedition which got blamed on Carelia as well. By the time we went to war there wasn't even much opposition to it. But what do I know, Ronan's just a knight.
