But what would you rather have. A place being carpet bombed and hundreds of people dying or a few innocent casualties from a drone strike? Yes all of us want 0, and that's the intention every day. I think drones do actually lower this number closer and closer to zero. We're also saying that we don't need to send US boots on the ground in as many areas as we had to.
It's scary to think about it but imagine if we have really small drones that can target individuals. Remember the first Ant-man movie? Something that small that's equipped with a toxin syringe. Send in a swarm to make sure at least one hits the target. That should reduce civilian casualty provided the drones can accurately identify and tag their target.
The scariest is when people discuss technical aspects of a war but avoid discussing the motivations. Society of psychos.
I tend to have a pessimistic view of human nature. People have always went to war and even outside that, continue to kill each other. Nations will always find reasons to quarrel and some of those will result in armed conflicts.
Having the option to do that in a "less" messy manner can only be a positive since it'll reduce the number of people hurt in the crossfire. I'd rather have countries dropping microbots on each other instead of nukes.
