It's been more than 60 years since the last world war. Society has become more globalized than ever. We (the Western world) are living in more luxury than kings were, a century ago*. I honestly can't see us - humanity - live for another half a century without major conflicts. There's just too many people on earth - we're on or over the edge of what is sustainable. China is growing out of proportions and so is India. Clean water will become very valuable. In Holland, where I live, much of our resources are imported. Even a lot of the meat and general food. The Western society is based on the ridiculously low prices of transportation for almost all resources, most importantly food. I think the chain can easily been broken and war is inevitable. This is not to mention how our weapons are more effective and deadly than ever before in history. Although it's not exactly a daily issue for me, I very much doubt we're going through the first half of this century without a major conflict. Opinions? *Might be a slight exaggeration, but you get the point.
