A bomb which was equal to 13,000 tonnes of highly-explosive bombs, used to make the Japanese surrender, but also killing many lives, cannot be justified. When the highly-explosive bombs were dropped in Dresden, everyone had thought of this as very affective. But imagine how bad the atomic bomb would be, which could destroy a city only just by its radiation, let alone the actual explosion. President Truman of America made a decision of using the atomic bomb and it is considered as a war crime.

Actually, the President had used two kinds of atomic bombs and was not sure which one was more powerful, so he tested them out in to cities in Japan for the first time.
As for the radiation after the bombing, it caused a lot of chaos. Even a few months after the atomic bombing, the poisoning from the radiation sill affected many lives. This radiation is affecting the people at this time, as the illness had been passed through the children of the real sufferers on 6th August and 9th August 1945.
But there is a thought, that if the atomic bombs were not dropped, war would have carried on, with all the bloodshed, and another million dead.
In general, and also in minds of many people, there was no necessity of using atomic bombs to stop and convince the Japanese to surrender. As the Americans thought that if...
