Yes, just as the minors are a polity right now. And their culture is considerably better than the former, given we've influenced them over a considerably longer period of time and they don't actually practice sacrifice and I believe they have a similar god to Crow. They also work and live on pretty similar terrain as the Ymaryn.
The Minors are not however, a civilization. No history, no administration of their own, only the Xohyr priest teachings and ruling. They don't really have any idea what to do.
I just don't see where you're coming from where having them as a vassal is a bad, given what we've seen of them historically and the similarities. Regarding them breaking away, that's just a poor argument. We have plenty of traits to mitigate such a thing, and we're facing that very same risk from other polities like the Lowland minors and Hatvalley.
The problem is the timing of them as a vassal is bad. We don't have the attention to spare to cope with such issues when we're still far from done with the Lowland Minors.
If we only had Hatvalley or Lowland Minors to cope with, then maybe. But we have a crisis, so we can't hold onto them satisfactorily, especially if the Swamp Folk take a swing at their southern holdings.
The land grab idea is awfully presumptuous as well, given there's zero indication that's what is going to happen, plus in the event of you being right all but assures they're going to come attack us back for the land to reclaim the mines given it's strategically necessary. At which point, they just become a vassal then. Frankly you're calculations seem off, as IMO the chance of the High Kingdom breaking out of vassalage in a war is lower than the High Kingdom warring against us to reclaim their strategic goods.
The land grab is predicated upon a few known factors:
-Sending the Red Banner through Hatvalley would make it a battle where they can't leverage quantity, and we have Iron armed heavy infantry versus their medium infantry. It's a fight that favors us.
-Logically you'd grab the land you are occupying. If we sent the Red Banner to Hatvalley, then they're going to be taking the Hathatyn Pass, which was explicitly laid out in a previous turn to be the Hathatyn mines that the Highlanders were after.
-The Highland Kingdom has better odds of breaking out of vassalage, because they'd retain their own mines unless we take further action to split the mines off from them. Which would be against Lords Loyalty
-The Highland Kingdom has poor odds of retaking the mines because...how the heck are they going to attack a superior quality force without any metal weapons?
It is slightly annoying you were one of the ones hollering about administration issues and no new provinces, and yet, here you are voting for conquest of territory which we don't really need; that'll take actions that we don't have to spend, when we're facing various crisis and other wars are occurring too.
I'm not an ideological voter. The side being backed changes based on circumstances, and the current circumstances is:
-We have Highlanders, Swampers, and Thunder Horse taking a swing at us from three different directions at once while the Thunder Speakers are waiting for an opportunity.
--Highlanders
---We can take the Highlanders permanently out of the war by full conquest. According to AN this will be difficult, even with the Red Banner, and we know vassals can explicitly break away when under stress(whereas a full province cannot unless we suffer full fracture)
---We can take the Highlanders semi-permanently out of the war by taking their mines. According to AN this can potentially finish in one turn if we commit the Red Banner in the right place. Odds are this will finish by end of next turn at worst, as the mountain pass is the strongest terrain for the Red Banner, and right next to our Hatvalley colony for support. They will not be able to fight us until they obtain another source of metal.
---We can take the Highlanders temporarily out of the war by fighting for reparations or humiliation. They will rejoin
--Swampers
---Nothing we can do here really. Their core lands are out of range.
--Thunder Horse
---We can let the vassals take up to the river and defend along that boundary. Won't stop them, but it helps.
--Thunder Speakers
---Nothing we can do here but look too strong to swing at.
-We have the administrative control issues in remission, which gives us room to take some risks here.
--We can spend the risk in settling far eastern Redhills to bridge to Lowland Minors and start work on their cultural unification, but we don't have the actions to do so
--We can spend the risk in taking the Highlander mines, which will cripple their warmaking capacity if successful.
That, is the logic behind this. Taking the mines of the Highlanders is the fastest way to defang them for the next 10 turns, which changes things from Defend Three Directions to Defend Two Directions.
This is a substantial qualitative difference in our ability to manage the lowland war.
