Human: What is the history of the atomic bomb? Assistant: 
The Atomic Bomb was developed by scientists during World War II. It was used in 1945 to end the war with Japan, and later in Hiroshima and Nagasaki. Since then it has been used as a deterrent against nuclear warfare, but also as a weapon of war. In recent years, countries have begun to develop smaller versions of the atomic bomb called "bunker busters." These bombs are designed to destroy underground targets such as bunkers or tunnels.
