As Song China, I attacked Jin and conquered a strip of land wrapping up Jin capital and also diploannex Korea and get its north part while south part remain in Jin hand, then the Mongols come and conquered all the reachable parts, now the problem is the Mongols don't bother to conlude peace with Jin so the alliance of me with Mongol and the war which I don't take part in last for 300 years and effectively "freeze" the mongol AI, as a result, Vladmir start attempt a WC, stretching from the stepp to west Europe, reaching a bad boy of two hundreds something. So I want to ask should the mongol AI not be so furious?
