The World War II ended with the event that America dropped two atomic bombs on Hiroshima and Nagasaki on 6th and 9th of August 1945 respectively. At that point of time, a majority of American citizens believed that dropping the bombs was absolutely necessary. However, it is an open question to historians as well as politicians whether atomic bombing on Japan was justifiable.
Many atomic bombing supporters argue that the use of atomic bomb helped reduce the casualties compared to an invasion of Japan. As president Truman stated, the invasion of Japan could lead to about 250000 to one million American deaths. Millions military and civilian casualties were also expected. Moreover, Japan had extended the drafts, including men from ages fifteen to sixty and women from ages seventeen to forty-five. It added 28 million people into the military. Japan also ordered disposal execution of all Allied POWs, including 100000 people, if any invasion of Japan took place. Therefore, dropping the atomic bombs instead of invading prevented the massive casualties on both sides.
Another argument supports the atomic bombing is its ability to warn the world about the danger of using atomic bombs, or other weapons of mass destruction. In another word, the immediate use of the atomic bombs convinced the world of its horror and prevented the future use. The evidence is that the United Nation controlled the production and testing of atomic weapons to prevent the use of atomic weapons against humans. Furthermore, it helps keep the world peace in a sense that a nation does not dare to use the nuclear weapons as they are aware of that its opponents may be developing atomic bombs also and the use of it may lead to mutual assured destruction. It is so powerful that after the first use, it was never used again. Hence, dropping the atomic played a role in attracting humans’ attention on the use of atomic energy.
However, America did have the alternative choices to force Japan to her...
