I always found the extraordinary loss of life in the First World War very moving. I remember learning about it as a very young child as an eight- or nine-year-old asking my teachers what poppies were for. Every year the teachers would suddenly wear these red paper flowers in their lapels and I would say 'What does that mean?'
It depends on the situation. I mean on one hand there's the argument that people should be left alone on the other hand there's the argument to wade in a stop slaughters in places like Bosnia and Kosovo and what we probably should have done in Rwanda.
