If there is a shooting war with large casualties between A and B, how involved does C have to be on one of the sides to trigger a resolution? From least to most

• Complete neutrality

• Verbal support only

• Economic support

• Military research, advisers

• Sending weapons, trade blockades

• Small independent battles

• Full on independent battles

• Shared military control

@Ernie I would say military actions that can be seen as having the same strategic direction

What is the threshold for deciding that war has occurred?

@Ernie good question, perhaps it is already happening

How does "Other" work here? Would it resolve that way if another country is seen to supplant one of these 3 as a great power before war begins, or are these 3 set for the purposes of this question so Other just contains "all against all" or one or more sitting out?

@JakeDennie Yes, it's some unpredictable scenario, such as another country become a superpower that pass any of these 3 for military and resources
