In Yugoslavia we were told we were not only naive idealists in wanting war criminals to be prosecuted but that we were actually standing in the way of a ceasefire which would save more lives. The idea was that, by giving amnesty to these ruthless warmongers, you would give them an incentive to stop killing. I found that incredibly naive, never mind cynical. Having been on the ground and having met with these ruthless killers, I knew the only thing they understood was the language of force.
