The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki in August 1945, killing 210,000 people—children, women, and men.
President Truman authorized the use of the atom bombs in an effort to bring about Japan’s surrender in the Second World War. In the days following the bombings Japan surrendered.
The Manhattan Project was the US government program during World War II that developed and built these first atomic bombs.
Detonation of these first nuclear bombs signaled arrival of a frightening new Atomic Age.
I hope this works!
