“
In 1984, I had another conversation that had underscored this point to me. Herb Okun, the deputy US ambassador to the UN, had come to his post after serving as US ambassador to communist East Germany. “What’s it like there, Herb?” I had asked him. “Oh, nothing much,” Herb answered. “They live in dilapidated housing, drive funny little Trabants, drink vodka all day while watching eight hours of West German television.” “What!” I asked in disbelief. “What did you just say?” “They watch eight hours of West German television every day and then drink themselves to sleep,” he repeated. “You mean to tell me that watching eight hours a day of West German television doesn’t have any effect on them?” I asked incredulously. “None that I can see,” Okun answered. “Herb,” I said, “that can’t be. It’s just a question of time until the cracks will appear.” The conversation made me recall an engineering course I took at MIT. We loaded a small model bridge with steadily increasing loads and photographed the process. The bridge held fine, until it suddenly collapsed. Yet upon closer examination of the film we could see tiny cracks propagating in the structure well before the fall.
