[@Irredeemable] In regards to the Navy, Ronto has a pretty large riverine and lakebound fleet, mostly for defensive purposes and protecting trade. Blue water naval stuff is mostly handled by PageMaster's dudes, which actually exemplifies something that's fairly common in Ronto - one of the ways they've managed to be so effective is through smart delegation, even if that means passively delegating an unofficial 'job' to another nation-state. The Red Devils, for example, operate fairly independently, and much of the army, which it has a command structure, emphasizes ability to operate independently yet cooperatively, because of the way I have the Canadian military going guerilla when the Americans invaded.

As for defeated foes, Ronto's policy could be described as fairly light, barring treatment of US government personnel and especially egregious raiders. Lots of them get firing squads. Negotiating with an organization like the Enclave, in that it tries to represent the pre-war US, aren't so much an unlikelihood as much as they are an impossibility. It's shoot to kill or prison camps for them. For other people, though, there's a lot of 'forgiveness' offered, and unique cultures that have joined Ronto (such as some tribals in the Southern Ontario region) are given votes and all like you might expect, but they're encouraged to keep their own cultural identities intact. Ronto's policy towards conquered people or groups that accede to them, then, can generally be described as this; "they've survived this long. We'll help where they want it, but they must've been doing something right."

I think that would be a (if not the biggest) point of contention between Ronto and the Confederacy, barring debates over who has rights to Southern Ontario. Ronto might generally respect multiculturalism, but the country is still generally pretty certain that it's got morality figured out. Sometimes that's for the better (I'd argue it is in the case of opposition to slavery), but sometimes it's for the worse.
