If we as a nation played the way Hussein and Arafat play, then Iraq would be a glowing glassy plain right now. This quiet Earth, this turning wheel of a cosmos cares not. Whether we go on or not matters hardly at all, except to us. Well, some of us, anyway. News is about unhappy people.
Revolution is about a lot of unhappy people.
There aren't enough unhappy people yet. But there's a tipping point, though probably not a balance. The universe gave us a place to live - a lot of us do that quite badly. However, it's been less bad than on average over the last 150 years or so. Probably it's going to be worse again one day soon.
