Nuclear terrorism is still often treated as science fiction. I wish it were. But unfortunately we live in a world of excess hazardous materials and abundant technological know-how, in which some terrorists clearly state their intention to inflict catastrophic casualties. Were such an attack to occur, it would not only cause widespread death and destruction, but would stagger the world economy... [creating] a second death toll throughout the developing world.

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.
