Explanation:
The first nuclear weapons to be used against another nation were dropped by "the United States during World War II."
This is evident in the fact that during world war 2, the United States B-29 bomber plane otherwise known as the Enola Gay in August 1945, dropped its first nuclear bomb over the city of Hiroshima, Japan.
The nuclear bomb led to the death of about 140,000 people in the city.
