Taliban Outpost vs School

This joke plays on the grim reality of drone warfare where the operator might not see or care about the difference between civilian and military targets. It's dark because it highlights the dehumanization of modern conflict, where the person flying the drone has a disconnected view of the consequences, making the distinction between a school and a military outpost insignificant to them. The punchline is that the speaker doesn't know or care about the difference.
