There was a lot of maneuvering on the part of the Roosevelt administration to get the stars aligned so that that attack would happen. There's just no question about that; you don't even have to look at the decoding of diplomatic cables or anything else. FDR's own admiral thought it was a bad idea to have the fleet confined in one place way out in the middle of the Pacific.

Wikipedia is just an incredible thing. It is fact-encirclingly huge, and it is idiosyncratic, careful, messy, funny, shocking and full of simmering controversies - and it is free, and it is fast.

History isn't a seesaw. If you have a really bad regime on one side, the actions on the other side don't automatically become good. It doesn't work that way.

One's head is finite. You pour more and more things into it - surnames, chronologies, affiliations - and it packs them away in its tunnels, and eventually you find that you have a book about something that you publish.

But spending your life concentrating on death is like watching a whole movie and thinking only about the credits that are going to roll at the end. It’s a mistake of emphasis.

What's somewhat puzzling is that Churchill himself knew what the reaction would be to any sort of aerial attack on cities, because in 1938 he said that in a future war British cities would be attacked by bombing, and that the response would be that all men would want to join the fight because they would be so incensed by this cowardly manner of attack. Which is a very natural response: when something drops on you from the air and blows up a bunch of buildings and kills people in their sleep, the reaction is going to be rage, confusion, and a search for something to destroy in retaliation.

The great thing about novels is that you can be as unshy as you want to be. I'm very polite in person. I don't want to talk about startling or upsetting things with people.
