Third-party intervention in the presence of supreme values

I set out a model of third-party intervention in which parties to a conflict can have supreme values. An attacker can decide to use own-population civilians as human shields against a defender. A third-party adjudicator can find fault with the defender for measures that harm the human shields. The criticism is an incentive for the attacker to use the own-population human shields. The supreme values relate to the value placed on the lives of the human shields. I describe the possible equilibrium outcomes.
