"How can a human being with any claim to a sense of moral responsibility deliberately let loose an instrument of destruction which can at one stroke annihilate an appalling segment of mankind? This is not war: this is not even murder; this is purely a crime. This is a crime against God and humanity which strikes at the very basis of moral existence. What meaning is there in any international law, in any rule of human conduct, in any concept of right and wrong, if the very foundations of morality are to be overthrown as the use of this instrument of total destruction threatens to do?
