Nah, I'm not talking only about that case. I played another game and this time war started over Suez. However Democrats stayed completely out all the way to the end (played till 1959). Occitanian revolution somehow failed, Switzerland didn't trigger anything and Russia never went to war with Lithuania.
We were crushing HRE and yet they never used that chance. While player might declare the war by himself, some sort of generic CB available at later dates for AI is needed to stop alliances from just sitting there if early events fail.
Although may be I'm just horribly unlucky, I don't know.
That's really unlucky.
There's like half a dozen hotspots in the events, besides simple opportunity wars.
