I have come to realize that a lot of our work would make the difference between war and peace, and it’s work that in a way is my passion because I know we can — not only through our work, but through my work and other people who are doing similar work — create a safe and more humane world or we can usher the beginning of our destruction. Some people call it “God’s work.” I don’t call it that way. I call it the work that — I cannot see that I would stop doing as long as I am able to do it.
