Peacekeepers = minerals keepers too.
Discussion
Hierarchy be like: Mineral Keepers -> Politicians & UN -> Peacekeepers -> Local Population
Peacekeepers might take relationships with the locals more seriously if they were the ones keeping the minerals they're "securing" along with the population.
Instead they get fobbed off with lousy pay, worse food, and near-total impunity for whatever they might want to inflict on locals.
We call this "Democracy". Sometimes "Stability" or "Women's Rights".
