Both remain below the threshold of combat. They differ in whether the dispute is resolved or simply remains open.

A 94% chance the coming year stays below the threshold of combat — direct great-power war the overwhelmingly unlikely outcome, the tail running through the flashpoints rather than a bilateral choice to fight.
