Killing is killing. It's not nice.Killing enemy soldiers in the trenches is terrorism? Why? Was he waving white flag? Did he try to surrender? What if he was performing a reconnaissance or an act of sabotage?
Or is it because of the drone? So when is using drones acceptable? When bombing enemy infrastructure only? If so, I wonder if Russians never used their drones to kill Ukrainian soldiers. I mean their "Orthodox brothers".
I do think that drone warfare is uniquely harmful to the operator. It's one thing to enter the battlefield risking your own life. Even this often sears the souls of men who participate.
It's another sort of thing to drop bombs from a jet on people you'll never see.
And it's a whole other deal entirely hunt remotely, dropping bombs or missiles with effect that you can't help witnessing. A lot of drone operators end up seriously messed up. I'm not saying it's more or less moral than all the other ways men kill each other. It is unique in some ways.
All the fangirling for drone porn from the war in Afghanistan was a horrific moral failure for the Righteous Americans. Someday, that all comes home...
