August 6th marks Hiroshima Day, a solemn occasion dedicated to remembering the atomic bombing of Hiroshima, Japan, in 1945, concluding World War II. The devastating bombings claimed the lives of over 200,000 individuals within seconds and left thousands more injured.

Seventy years ago this week, the United States dropped an atomic bomb on Hiroshima, resulting in the tragic loss of over 140,000 lives—surpassing any other single event during World War II. The bombing obliterated a significant portion of the city, including a school where more than 80% of the children who perished were between 6 and 11 years old.
