The question becomes, because we're remotely far away from the territory we're about to bomb, does it make it easier to do it? That it is an important question, and the military is asking those questions.

Having been in the military myself, there is an awful moment when you're in this moment of conflict.

I am a story-teller working with a craft. My job is to use my craft - which is a different thing to my race - and tell a story well.

When I see big movies that are only about good versus evil, and the good guy wins, I only can think we're in a far more complicated world than that. I frankly think that this binary philosophy is actually a dangerous way to look at the world.

I think if you read the story as bad guy turns good guy, then clearly it is a cliché. But my experience, when I spent three years working with young people in the townships on issues principally around HIV/AIDS, is that people are usually neither entirely good or bad. They are usually variations of both. Just because someone is a carjacker doesn't mean they are a ruthless cold-blooded murderer.

The question becomes, because we're remotely far away from the territory we're about to bomb, does it make it easier to do it? That it is an important question, and the military is asking those questions.

And for the people who promote drones as the answer to everything, there is a danger from being distanced from the reality of the ugly mess of war.
