Oh, undoubtedly more in ignorance than in humour - I'm not that clever. (It wasn't even meant to be funny - sarcastic maybe).
There could well be some truth in what you suggest, my post should be seen as merely an observation on the way you put it across. You seem to have quite strong views and theories of why the Americans did what they did. But I fear that if we were to dig too deep then all countries involved in the war would find much of which to be ashamed.
Your view that it was not necessary to destroy such a large city is a very difficult one to either support or defend so many years later in 2010 - but I'm afraid I've spent too much time in the company of a former Japanese prisoner of war to be able to argue rationally and without emotion on this subject, so I will not.
Speaking of which, there was a TV program on not many months ago where a daughter took her father, a former prisoner, back to one of the death railways and he met the local community. To see that man show such dignity and respect - almost forgiveness and understanding - in the presence of the Japanese people, despite what they did to him and his colleagues and despite what we did to these two Japanese cities, made me feel very small and humble.
