Napoleon once said that all generals fight the last war. I don't actually know if Napoleon said that, but he's the general you use when you want a general to have said something, so he's who I'm using. It's like when people say, Hitchcock said, never cut away from the gun, even though I don't think he said that and I don't think that's a rule, even. The rule is, if you're going to make up a rule, always attach someone's name to it who has a lot of juice...
