In 1988 Keith visited the Hiroshima Peace Memorial Museum and wrote the following in his journal:
We all went to visit the Peace Museum & Memorial, which is a vivid documentation of the horrors of Hiroshima. It is impossible to imagine the magnitude of the bombing until you personally experience this museum. I had, of course, read about and seen some photos of Hiroshima, but I never felt it like this. It is incredible that this destruction was caused by a bomb that was made in 1945, and that the level of sophistication and number of nuclear warheads has increased since then. Who could ever want this to happen again? To anyone? The frightening thing is that people debate and discuss the arms race as if they were playing with toys. All of these men should have to come here, not to a bargaining table in some safe European country.
