What about setting up an occupation government to restore public order and economic self-sufficiency to the Tortun while at the same time setting up a roadmap to independence as a unified republic for them once they meet certain goals? I mean, i am not sure if something like that is conceivable for our society, but we can in fact release clay we have gibbed, and being the ones that finally give them their national unification as a Republic ought to make up for some of the bad blood that this war has generated.
Easy enough in theory yes.
But chances are we would never be able to afford it. And like not even in terms of resources, but simply in terms sheer Political Will.
The fact of the matter is that the Tortun Lands are ridiculously resource rich, and we will have spend millions of lives to get it and hold it. Now remember, our generals, military personnels and Nobles are all in the military, since exemplary military services gives immigrants and ordinary people the opportunity to gain titles and lands to rule over. And we have just raised several huge armies which have been crushing two other colossi national warmachines due to personal initiative.
This means that by the war's ends, we will have a shitton more minor nobles who have earned enough merits to ask for new Lands, newly titled military officers who will want lands and etc. And all of them would have spent blood and sweat and lost friends and loved ones to take and hold Tortun Lands, which creates a bit of an problem of entitlement.
Now, we could just have them settle kyberia, but Kyberia is still poor and backwater, and its resources are underdevelopped, but Tortun Lands even ravaged are ridiculously productive. The exemplary officers from this war are not going to settle for poor ass lands when they feel that they have earned the right to have much more.
Basically assuming we could even afford the PW cost of not taking Tortun Lands, narratively good chances that Nokly gets deposed in a military coup afterwards.
