Fifteen years ago, a business manager from the United States came to Plum Village to visit me. His conscience was troubled because he was the head of a firm that designed atomic bombs. I listened as he expressed his concerns. I knew if I advised him to quit his job, another person would only replace him. If he were to quit, he might help himself, but he would not help his company, society, or country. I urged him to remain the director of his firm, to bring mindfulness into his daily work, and to use his position to communicate his concerns and doubts about the production of atomic bombs.
