Glenski, the use of the atomic weaponry at that time saved hundreds of thousands of lives. Or more. The Japanese elite had the lower classes fully geared toward total conflict and taking the islands would have been a foot-by-foot endeavor in the larger cities, and a mile-by-mile (km) endeavor out in the countryside and smaller towns.
Of course, you could change my view of that matter if you could provide me with specific information about who in the upper tier of the governing elite in Japan were discussing amongst themselves how to change the thinking of the lower classes doing all the fighting and dying that maybe the horrid Americans and British and Russians were not animals that deserved to die because they wanted the conflict to come to an end. I'll be very happy to study what you can provide, but that probably requires a new topic/thread. Unfortunately, at this writing all my studies point to the use of that atomic weapon as saving a whole bunch of lives on all sides.
NOTE: You might be so crafty with your use of language as to disguise your true intent when you wrote about you are not stating whether it was either good or bad, BUT it clearly appears you are making a statement that it was a bad decision by President Truman. I give you credit for excellent language usage, thus draw my conclusion that you are purposely using a very thin curtain of words to hide your true feelings on that decision by the United States executive branch to authorize the use of that weapon.

Muz1234, is there a possibility that certain matters that arose in your own nation back then has left a kind of burden upon your view of the nation of Japan?
SomeCallMeChris was quite correct in making the point that really bad stuff has been done over the years by the British folks, but the British folks aren't the only ones that can be placed into the category of doing bad stuff over the years. If you want to cease studying about other peoples in other nations because their parents, grandparents, or further back did bad things — well, have your own people in past years been so super nice and so cool and never did anything bad?
