Was the bomb a necessary exil during World War 2?

Answer 1

During World War II, the use of atomic bombs to defeat Japan continues to be debated: was it necessary (as a 'necessary evil' or otherwise) or was it not? At the time, it is undeniable that Allied leaders were fearful of the casualties that would follow from any land-invasion of Japan. Moreover, they were not convinced that a land-invasion of Japan would even end the war. With these points in mind, it is very reasonable to consider the use of atomic bombs as sound and prudent, even if not necessary.
