Sometimes the AI hates you enough - prior wars, amount of damage done, or something else - that they would rather die than make peace. It doesn't happen a lot, though.
Thanks.

So AI can be suicidal sometimes.

I noticed I didn't get huge diplo hit, since several AIs already denounced Bismark, and I was friendly with few civs.
This game I mentioned took place in vanilla. Good to see that Oda's warmongering, forward-settling ways haven't changed.
But njmff's post raises another question that I'd like to see answered by the veterans here (although it's probably material enough for a different thread all on its own). How do you deal with the forward settlers? You know, those civs that have the temerity to plant cities near yours, and THEN declare war on YOU? And even the ones that don't declare war on you - those are actually worse since you have to do it yourself and get the penalty.
Either way, the problem is the same. The only way to get rid of those forward-settled cities is to take them from him, which will hit you with the warmongering penalty, despite the fact that he settled right beside you in the first place, which is something the other AIs should be able to understand, since they don't like it either when you (the human) do it to them. How does one deal with this?
Yeah, Oda can still be weird AI. Settles near you, complains that you settle near him (much like Elizabeth) then fallows by attack. He can be good ally sometimes tho, and won't be cranky, but it depends on how are your relationships with other civs. Alto, I always watch out for him since he backstabbed me several times in few games.
now about settlers. It's a luck factor like other member said, but there seems to be few factors that make the difference:
1. Relationship with AI. You can ask them not to settle and they will agree to it, if you're friendly enough. It seems to be in effect only after AI already settles near you tho.

(much like religion and convert)
2. You have a bigger military so you bully them by demanding they don't settle near them. Sometimes it will work, sometimes it won't. Seems to be less effective with warmongering civs. Siam can also refuse.


Orange will agree but still settle near you. Leave him to make Polders then capture his cities\steal territory with GWG.
3. Block AI's settlers - don't give open boarders, then place units on the titles you don't own so AI can't pass your land. If you figure out where AI wants to settle, you can use 2-3 units to block him and go in circle, AI can eventually give up (alto, it can still settle around the same era, so it's luck).

in one game I figured out that Elizabeth wants to settle on hill near my city, so I kept Swordsman on that hill. She was persistent tho, and kept that settler just sitting there for over 100 turns.

Oda also wanted that place (!?) but eventually settled near my city, soaking up some titles.

That city was first to get captured when we started a war tho.
4. Declare war and capture his settlers. This can hurt Deity AI really bad too. They immediately lose half of their advantage.
