Is there any way to work out if your allies will reject a call-to-arms defensive war ? (in the ledger etc)
I ask as my last few games have been ended by the AI obviously knowing that my allies won't join me (it's a computer program after all) with several different nations, and different allies - the only common denominator is that my major ally always refused to join my war. The foes I'm facing wouldn't have attacked me if they didn't already know that my one big ally would betray me. (ie: Byzantium + Russia: Hungary attacks me, and Russia betrays the alliance - they couldn't have won vs. Russia as my ally, so the AI obviously has a way to work this out)
For context, I always have royal marriages, 150+ relations, a diplo reputation of at least 1+ early game. This happens if my ally is at peace or in another war, doesn't seem to make much difference.
I'm hoping there's a logic to it !
I am not aware of a quick way to see exactly, if an ally would defend me against different attackers.
What I can do is the following:
In this example I am Mughals and Qara Qoyunlu is my ally. So I look for another ally of Qara, e.g. Mushasha. Then I pretend to declare war on Mushasha and look in the UI what would happen. I see: Qara would not defend him against me and I let the tooltip show me the details.
So I see all the reasons, positive and negative, in this situation. More info about reasons: Wiki: Call to arms
Alot of stuff and numbers.
The most common reasons for "betrayal" are money and negative effects from other wars, like occupied provinces, war exhaustion or low manpower.
In specific: To check the debts of a nation (without a diplomat available) I can either pretend to use "take on foreign debt" as diplomacy interaction, if I am a Great Power. Or look at the ledger, page 4 "score comparision", Adm. Rating, where each loan gives a score of -0.02.
Maybe it needs some expierence to see through all this numbers.
But nations with high and long lasting debts and/or those losing wars are highly unreliable defenders. Better to cancel those alliances and look for better friends, if available.
