It's interesting to observe the various conflicts that occur between people and nations. This article, from the Church of Scientology, describes what they are doing to bring peace in the Middle East, which I think is great. It shows that in many cases, conflict can be solved by simple communication.

For example, did you ever have the phenomenon of getting to know someone that you had seen around and had an odd opinion of? Kind of like some out-cast kid in school, some guy or girl you saw, but never new? And you actually get to know them. In most cases, you find out that they're really not as nuts as you thought they were! So what changed - well, not much - you just talked to them. Pretty simple, eh?

And if you read what Scientology has to say about that (communication), it's pretty interesting: here's some basic resources. There is also this page from their president, which expresses some of their basic views on what they are trying to accomplish.

Now don't get me wrong, I don't claim to believe that there are no truly evil people in the world: since some people seem to ceaselessly defy all logic and mercilessly insist that it's okay to destroy human rights and that it doesn't matter anyway, etc, etc. However, in many cases, it seems that basically well-intentioned people fall prey to their own lack of communication.
