Just come out of a lecture (im doing war studies) titled "why war? - logic, instinct and emotion". The lecturer covered a number of reasons for warfare, one of which he heavily discussed was aggression. Mankind is naturally aggressive and we seek violence. I'm not entirely sure I agree with this because levels of aggression vary in different societies, which demonstrates that aggression is influenced by cultural and social factors. But what I am wondering is, are wars rational and can wars be fought with rational calculation? I know this is not typical arrse fayre but I am hoping some people can help me work some thoughts out!
