Kurtz (Joseph Conrad) was more correct than he could possibly have known: "The horror! The horror!" Another reason why all young people should be exposed to the classics (as opposed to the tripe currently being fed to them as 'literature' because it fits an ideological schema or, perhaps even worse, it is deemed more "accessible", i.e. offering no challenge to the mind to give it something upon which to grow.)

Point taken, and it is a very good one, although, as many of the parties involved have died and documents have been released, it becomes apparent that all of the 'reasons' we were given for certain acts are not necessarily the ones originally supposed. The morality of using the atomic bomb, twice, will continue to be debated, and correctly so. Let's just agree that there are compelling arguments to be made that the second bomb may have been 'overkill' to achieve the surrender of Japan.
I would ascertain that it appears to have been the United States 'objectives' not necessarily 'their Allies' in the use of the atomic bombs, or, more specifically, the objectives of certain parties in power at various levels with respect to the geo-political landscape. If it seemed that I was suggesting that the Catholic faith in Nagasaki was a primary goal, I regret having appeared to do so.
I am suggesting that it is not outside the realm of possibility that it was one of the convenient side benefits, and, as such, it may have had to do more with the affiliations of those who made the decision to bomb rather than just 'winning' the war. Given the times we currently live in, and the number of public leaders who appear to be committed to establishing a World Order, it is possible to argue that the reasons you are told things are being done are not necessarily the actual reasons they are being done.
