At Arms Control Wonk:

Greetings Arms Control Wonk readers. I am yet another pasty, dark-haired contributor. I normally wear glasses too, but Jeffrey asked for a picture sans spectacles so that you could better tell us apart. I said, "Dude, your readers can look at satellite photos and tell the difference between a DF-5 and a DF-5A. Shouldn't they be able to tell us three apart?"
