WAS THE ATOMIC BOMBINGS OF HIROSHIMA AND NAGASAKI JUSTIFIED? A bomb which was equal to 13‚000 tonnes of highly-explosive bombs‚ used to make the Japanese surrender‚ but also killing many lives‚ cannot be justified. When the highly-explosive bombs were dropped in Dresden‚ everyone had thought of this as very affective. But imagine how bad the atomic bomb would be‚ which could destroy a city only just by its radiation‚ let alone the actual explosion. President Truman of America made a decision of

John Evans Mrs. Heilmann Honors English 9 April 29 2013 Atomic Bomb: Hiroshima and Nagasaki The atomic bombings on the cities of Hiroshima and Nagasaki were the first and only use of nuclear weapons in war. These two bombings were both conducted by the United States in an attempt to force surrender from Japan. It is estimated that as many as 200‚000 Japanese civilians died as a result of the two bombings‚ thousands more were also killed by radiation poisoning following the actual bombing. This

This indicates that after decades of the atomic bombing‚ the author can analyse the whole thing based on abundant research and investigation conducted throughout the 67 years from a new and longterm point of view. The source states quite objective analysis instead of subjective or extreme opinions‚ it mainly focuses on explaining the complexity of the situation at that time. The source analyzes several general reasons why the USA dropped the atomic bomb on Hiroshima and Nagasaki including ending the war at the earliest possible moment

In the case of the atomic bomb there has been a great deal of opposition to it: that it is not necessary to end the war and there are better alternatives to it. In actuality‚ the atomic is necessary to end the war‚ and it is not as “evil” as a weapon in war‚ as many seem to think. It will make the

alerted the US government to the possibility of an atomic bomb. President Roosevelt then set up a program to study uranium and the possibility of an atomic bomb. This started the series of events leading to the atomic bomb. American scientists‚ under this committee discovered that uranium-235(U-235)‚ the type used in the atomic bomb‚ is one part in one hundred and forty of normal uranium. Almost all of the initial work and studies into uranium and atomic bombs happened in New York‚ and as studies advanced

The Atomic Bomb Probably no other man-made object has wielded as much terror or destruction as the Atomic Bomb. Created‚ tested‚ and used during World War II‚ it brought about the end of that bloody conflict. Unfortunately‚ it also was the cause of much loss in human life. However‚ why it was created‚ creation‚ and use are very interesting‚ although somewhat sad‚ and offer many topics for study. The creation of the bomb was actually started before the war- early 1941‚ because the president

ALBERT EINSTEIN and the ATOMIC BOMB The physicist Albert Einstein did not directly participate in the invention of the atomic bomb. But as we shall see‚ he was instrumental in facilitating its development. In 1905‚ as part of his Special Theory of Relativity‚ he made the intriguing point that a large amount of energy could be released from a small amount of matter. This was expressed by the equation E=mc2 (energy = mass times the speed of light squared). The atomic bomb would clearly illustrate

the atomic bomb began. As time progressed in the war era‚ the bomb was fully developed as the United States dropped two on Japan. As the bombs demolished two cities in Japan‚ many people questioned if the usage of the bomb was necessary or not. The atomic bomb impacted the conflicts between the United States and Japan by forcing Japan to surrender the war‚ preventing Japan from evolving into a major threat to the U.S.‚ and by saving the U.S. from another powerful attack from Japan.
