Except, when all the nations and villages are allied and getting along just great, there isn't much use for military power... or I should say, that power can be cultivated on a different timetable.

There are still conflicts to be dealt with--bandits and town skirmishes and gangs--as we see from the missions they all go on, so their skills are still being utilized, just without the stress and tragedy previous generations had to endure.
