Unfortunately there's a huge crowd of people on the right wing of politics everywhere who believe that war is the inevitable state of humankind. There has always been war, they will tell us, and therefore there will always be war.
Well, there are a lot of things that "always were", and yet we've put a stop to so many. You don't see a whole lot of land wars in Europe or human sacrifice anymore, do you? And there a lot more "always were"s that we're slowly stamping out: genital mutilation; asbestos; honour killing.
The most telling comment, though, regarding the father of the man who died so recently in Afghanistan, is this one from the mother of another deceased soldier:
"You've gotta believe that what they did, they did for a reason," she said, adding: "I honestly believe they're there for a good reason."
It sounds sadly desperate, doesn't it? You gotta believe. You just gotta. They can't be dying and killing for no reason. No. No way.
