Let's put it bluntly:
- The attacks on Pearl Harbor at least made some sense at the time. They were attacks on military targets. And FDR had goaded the Japanese into attacking our fleet in the first place.
- The attacks on Hiroshima and Nagasaki have never made any sense. They were attacks on civilian populations. And in spite of US propaganda to the contrary, they were totally unnecessary. Senior US military leaders thought the attacks were barbaric, and they were right.
So Pearl Harbor will live in infamy? Apparently it will, but we ought to add to that infamy the actions and inactions of FDR which brought it about and/or failed to prevent it.
Or do we want to keep lying to ourselves?
