Is there any hope for Peace?

As you may or may not know, yesterday a bus station in the Indian Kashmir was attacked by militants. Today, a bus from that same bus station is supposed to make the first journey for a very long time from India to Pakistan across the Kashmir. This was to be the first tangible result of the peace talks in the area. But, like Ireland (and more recently the Middle East) peace talks don't seem to work. Next year will be the ninetieth since the beginning of the troubles in Ireland and we have only just about managed to get something resembling peace there. So, is there any hope for peace anywhere? Well, the answer looks like no, not for a long time. We are facing the same problems that we did in the 1920s and 30s, without the rise of Hitler and the Depression. Conflicts are breaking out all over the world and the body that is supposed to stop them (now the UN, then the League of Nations), is failing. So, what exactly is wrong with the world. Maybe it's the refusal of world leaders (not mentioning any names) to stop making war and destabilising countries (still not mentioning any names), or is it the growing lack of natural resources such as oil (still not mentioning any names). Or maybe it's just human nature, maybe there's something about us that means we have to kill our fellow humans. Is there? I don't know, what do you think, is there any hope for peace in our time?
