Answer:
The American people
Step-by-step explanation:
John Hersey wrote the book Hiroshima in 1946 shortly after the bombing of China by the United States of America. That singular act by the U.S ended the ongoing war between the two countries. Hersey wrote the account of the event detailing the extent of damage caused by the bombing.
The American populace who read this book was able to see in clear detail the extent of damage caused by the bombing. Hersey used pictures of the horrors committed to bring the story to life.
