-Except that is exactly what the Watchtowers are for. To help bring in those that are working outside our towns before they are attacked. We are not leaving them alone, we are about to hire 3 Mercenary Companies to help defend their towns. As to the ridiculousness of your West Wall scenario, how are we to be warned without the watchtowers? Why not have the Watchtowers in place so that West Wall doesn't burn down.
-If we build watchtower in our own territory it won't help West Wall that much since they are a colony and we can't dictate what they build. Here is a quote from AN
It will build in your primary territory, not your subordinates, but it will prioritize the most threatened areas.
So defensive policy will not help the build more watchtowers, they will have to do so themselves. By not sending a war mission we are effectively leaving them to fend for themselves.
Furthermore i said they might be killed but i said that our infrastructure will burn. This means people will suffer even if they might survive and recover. On the larger scale it will put back the progress of Gullvalley by decades if the colony`s infrastructure is destroyed. Furthermore i would like to keep the tribal mercenaries on the frontline away from the majority of our populace, since they may cause disharmony with their "barbaric" ways (compared to Ymaryn lifestyle).
-Again, you underestimate the importance of Walls to defend against attacks. It doesn't matter if they have an army if they cannot get in. This far from their core lands also means that they can't just leave their army there for years on end, or even months to wait them out. You are also completely ignoring how stretched their logistics are if they are just putting up a colony of their own this far north. We are not going to going up against a horde initially. Having some areas protected by walls and watchtowers create more flexibility than having war mission sent out because instead of having thousands of people watching over hundreds of borderlands, we can have half of that watching over half the territory, allowing more people to be moved around to where the actual attack is being place instead of sentry duty
-And those troops can be spared more easily if we have less poorly defended towns that we have to overfill with troops to defend properly. Having Offensive is very much about destroying the feelers because that is all their current logistics can send. We are at the very edges of their territory, they will not be able to send their full forces so readily especially since they also have many neighbors also looking for a sign of weakness. Going offensive means using a blowtorch to burn away dust bunnies
Those towns you speak of is in our territory and the battlefield will most likely be in the lands of our subordinates (who are not affected by our policy) so instead of sending aid to our peripheries we would be forting up our homelands far from the actual battlefields.
No the point is to prevent them from building up a significant army that may invade our lands, that might have siege equipment and jeeping them from forting up.
Us building them walls aids in many ways that I have outlined several times. Saving our peoples lives is vastly more important than their worldly possessions.
Not just worldly possessions, homes, jobs and food production would be significantly harmed by letting them run free on our countryside. It means that we would have to send food supplies to any area that had been sacked straining our supplies and supplie routes.
My plan increases the safety of all our lands because it sets our provinces on fortifications and warning systems while we are more at liberty to send the assistance they require, whether that be war mission, more long boats(so that they can better attack the invaders), support subordinate(if they require food and such), or anything else they need.
And as i said OUR lands will have increased defenses, but our subordinates don't count as our lands by the policy mechanic so they will be left to fend for themselves. If we end up being attacked from multiple fronts while in defensive policy, we will have to spend most of the kings actions to ride to their defense or switch to offensive anyway.
