What was the opinion of each of John Hersey survivors?

In Chapter Four, Hersey presents the two sides of the issue: some argue that the bombing was acceptable on moral grounds, because Japan and the United States were in a state of total war where anything goes. Mrs. Nakamura even says, "It was war and we had to expect it" (Chapter 4, pg. 109). However, others argue that it is morally wrong to use a weapon that deals so much destruction without the ability to discriminate between soldiers and civilians. This debate about the morality of nuclear weapons continues today, in a nuclear age that was set in motion by the event that John Hersey has investigated so thoroughly: the 1945 bombing of Hiroshima.
