So I was in Alexandria, Virginia the other day, attending an academic conference. Specifically, this was in a hotel two subway stations away from the Pentagon. There were military contractors everywhere.

It was a good reminder of two fantasy worlds: on the one hand, I live in Madison, Wisconsin, hometown of the only Senator who voted against the Patriot Act, a city once described by a Wisconsin governor as “30 square miles surrounded by reality”. So every once in a while it’s good to get out; to see what the rest of America is up to.

But being a mile from the Pentagon is not the rest of America. The place is pulsing with power. Contractors eating lunch in a little park puff on cigars in a non-ironic way: they’re smoking cigars, and they mean it.

The most surreal was this: an advertisement for the Lupus Foundation, with a little boy, who wants you to donate so that he can get better. You’ve seen those posters. But this one said: “Some day he’ll fight for his country. Today he’s fighting Lupus.”

And that’s when I knew I was in a strange place. People talk about “inside the beltway,” by which they mean the political world alternate reality. How about the alternate reality of militant charity?
