I used to tell the story about as a young man in high school one of the professors came in and put a broad white sheet on the board with a dot in the right hand corner and said, "Boys, what do you see?" And we all shouted, a black dot. He stood back and said, "not a single one of you saw the broad white sheet, you all saw the black dot." He went on to tell us to focus on the broader picture, don't focus on the negative.

Peace may indeed be a complex challenge, dependent on action in many fields and even a bit of luck from time to time. It may be a painfully slow process, and fragile and imperfect when it is achieved. But peace is in our hands. We can do it.
