““I had the mistaken idea, based on what happened in World War I, that we would stay out of the war, and it is very unfortunate that I felt like that. If I had been more convinced, as Wigner and Szilard were, that we were going to get into the war, I would have pushed harder to begin making the bomb. I figured out that roughly half a million to a million people were being killed a month in the later stages of the war. Every month by which we could have shortened the war would have made a difference of a half million to a million lives, including the life of my own brother.””
