Judging the bomb builders

The ethical aspects of the Manhattan atomic-bomb project, and the moral responsibility of the scientists who worked to make it success are discussed. Many scientists, who later campaigned against nuclear weapons, had no regrets about having worked on the Manhattan project. The fact that the bomb may have spared others from subsequent Japanese brutalities, and may have spared Japanese casualties from a longer war, does not count. Anyone who declines to express their moral thinking is said to be behaving in a morally irresponsible way.
