Two very different quotes, (click on them to hear them), from those who were, and who thought themselves, responsible for the hundreds of thousands of people, mostly civilians, who were killed either directly or indirectly by the nuclear bombs America dropped on Hiroshima and Nagasaki.
To my mind Oppenheimer was not responsible. Such technology would have been developed by others, and turned into weopons. Truman on the other hand – well, he was responsible. And if the killing of a single person is wrong, how can you ascribe in words a sufficient degree of wrongness to such an act as ordering nuclear weapons to be detonated over population centres.
I wonder if anyone in the entire future history of mankind will be directly responsible for so many simultaneous human deaths as happened in those two brief flashes of manmade sun fragments.
