I think that Ian's greatest skill in leading was that he was happy to deligate. No need to watch the Cappellan March personaly with Hanse on the job. My personal thought is that with his attention undevided, Hanse is able to do more to stop Hasek's plotting, and so the Cappellan March becomes more stable, not less, for Ian's leadership. Of course, with Ian and his millitary attention on the DC bourder, one can expect plenty of action there, if not nessissarily progress (Takashi is hardly a push over and Kat's unlikely to distract too much attention in the years leading up to her peace innitive in 3020). And as for the other parts of the nation, like the economy, they'd be in the hands of ministers who are likely to be more expert in their fields than a warrior prince anyway, and so again, probably better off, asside from the economic drain of a continual war with the combine that is.
