Atomic Attacks on Japan 

I'm not sure this section is a good example of revisionism. The reason is, the "old" view is still widely held and valid, the US certainly did drop the bomb to end the war quickly - it may have also had other motivations, which are now coming to light, which adds to a more nuanced picture of events. There will always be new perspectives and theories, just like in Decline of the Roman Empire, but these are not really revisionistic. Revisionism, strictly speaking, is where you take an established idea and discount it based on new evidence.  Otherwise it is just the normal process of better understanding the many nuances and complexity of history. So I guess the question is, is there a school of thought saying the US did not drop the bomb because it wanted to end the war early?
