Japanese strategy for Manchukuo

[NVI]

Playing Manchukuo in historical mode, I was genuinely surprised that Japan went for a large number of Manchuria-related foci early on. Looking at the game files later on (common/ai_strategy_plans/JAP_alternate_strategy_plan.txt) I noticed this only happens when the player is controlling Manchukuo.

I am very much wondering why such a wide-ranging strategy exists. I think the strategy would, broadly speaking, make sense if Japan pivots to it after the player has chosen the Obedience focus. As it stands, many players will play Manchukuo with the goal of breaking free, and the strategy will end up hurting Japan both in terms of Manchukuo being stronger, and of opportunity cost.

I've played Japan with 1.5.1 in non historical mode and was worried that Manchukuo went straight to the independence focus tree. Although they are able to do the final focus tree for their independence war, they didn't use it, even after I started war with China. I am not sure, what they waiting for or if there is some script behind it.

Maybe someone can share his/her experience, if Manchukuo AI is more loyal if I use the Japanese focus tree that helps Manchukuo.

I am pretty sure that if player is Manchukuo Japan is more likely to aid you via focuses

Yes, that's true. But that's not what I meant. The question is, how can player of Japan in non historical mode influence Manchukuo, that they stay loyal?

I didn't find anything that modify MAN's AI loyalty
Developers didn't even put MAN's history focus data in Hearts of Iron IV\common\ai_focuses
So...basically, it's just like MAN has 60% chance to be loyal, and 40% chance to be assertiveness. Historical mode on or not...

If AI picked assertiveness
Then, AI will check MAN's military power against Japan's military power
If AI thinks their military is at least 30% as strong as Japan, they go rebel no matter what...
If AI thinks their military is weak, they will act just like normal which we can consider they are loyal, instead of worry about them like your subjects in CK2

Very cheap implementation... I guess that's why we lack of diplomatic depth in this game...
