The other thing that happened was my last military assignment - this was in the air force; I had enlisted in order to avoid being drafted as a private, and of course I only practiced medicine or psychiatry in the air force so I was never in any kind of violent combat.
Again, I was influenced by my father, who was very much an atheist and took pride in combating the traditional or orthodox forms of Judaism, which his parents and which my mother's parents were very steeped in.
It was because of my deep concerns about nuclear weapons that I went to Hiroshima. And then I was astounded in Hiroshima to find that nobody had really studied it.
And I managed to arrange to get some research support and to stay in Hong Kong for another year and a half, interviewing people coming out of China, both Westerners and Chinese. And that was my first real research study on thought reform or so-called brainwashing.
But when I went to Hiroshima and began to study or just listen to people's descriptions of their work, it was quite clear they were talking about death all the time, about people dying all around them, about their own fear of death.
Every adult in the world has some sense that he or she might be obliterated at any time by these weapons that we have created.
