Answer 1

Answer:

President Harry S. Truman, warned by some of his advisers that any attempt to invade Japan would result in horrific American casualties, ordered that the new weapon be used to bring the war to a speedy end. On August 6, 1945, the American bomber Enola Gay dropped a five-ton bomb over the Japanese city of Hiroshima.

Answer 2

Answer:

The explicit reason was to swiftly end the war with Japan. ... A few days earlier, just 16 hours after the U.S. B-29 bomber Enola Gay shocked the world by dropping the first A-bomb known as “Little Boy” on the Japanese city of Hiroshima, the White House issued a statement from President Harry S. Truman.
