I'm reading a just published WW2 book "The Fleet at Flood Tide" by James Hornfischer about the Pacific war 1944-45. Almost the very last paragraph in the book is a statement by Paul Tibbets he had originally made to Chicago Tribune columnist Bob Greene during an interview in 1998:
BG: But what if the scientists had declared the bomb not ready--or if President Truman had decided not to give the order? What if the war had been allowed to go on, and the battlefield deaths had kept mounting?
"If we hadn't flown our mission, I think mankind would have lost a lot," Tibbets said.
He knows that there are some who, all this time later, disagree with him. He knows that there are some who continue to be highly critical of what he was asked to do on that August day. His response to that is as direct as Tibbets himself:
"Those people never had their balls on that cold, hard anvil. They can say anything they want."
