"reminded him of photographs of Hiroshima"

Hiroshima is a Japanese city that was hit with a United States-conducted atomic bomb on the 6th August 1945. A nuclear weapon was also dropped on Nagasaki on 9th August 1945. This followed the Japanese government refusing to surrender after the Potsdam Declaration of July 1945. Within two to four months, 90,000-166,000 people in Hiroshima and 60,000-80,000 in Nagasaki were killed. Around half these numbers died within the first day from burns and debris, but large numbers died from the effects of burns and radiation sickness. On the 15th August 1945, Japan surrendered to the Allied Powers, ending the Pacific War and effectively World War II.
