Well, in every city there are military establishments. It is easy to understand that in America, endeavours were made to prove that the attacks on Hiroshima and Nagasaki were motivated by the wish to destroy military targets in those cities. In my opinion these were tales to soothe the American conscience and to deceive the rest of the world. I think history bears this out. When the Manhattan Project started, five cities were selected to be destroyed by the atomic bomb. They were not to be attached with conventional weapons. They had to be intact cities, to be destroyed by one bomb. The first on the list was Kyoto, the city with the world-famous temples. After strong protests from the more sensitive and cultivated people in the American government, Kyoto was struck from the list. Just because of its temples. Later Nagasaki was destroyed. It was the very place where Christianity had gone underground in the seventeenth century. A pretty large Catholic community held its own there for two centuries, and came into the open again after the Meiji restoration. Some people were left with the feeling that the Buddhas in Kyoto had protected the city better than the God of the Christians in the city of Nagasaki.
