1) Drones have increased massively in use by the US in Afghanistan and Pakistan, killing many militants but also civilians. Laws of war have not caught up with drone technology.

3) Issues for discussion around drones include whether their advantages in warfare make their usage acceptable, and what laws should govern drone combatants.
