Drone warfare creates a **moral hazard** by shifting costs to others. [definitional]
The main effect is to introduce a massive bias into his decision. Any agent who can take action with fewer risks to himself or his camp is likely to adopt a riskier pattern of behavior—that is to say, riskier for others. Similarly, the drone is a classic “moral hazard”—a situation in which being able to act without bearing the costs of the consequences relieves agents of responsibility for their decisions.
