This week the U.S. State Department officially quit using the term "rogue states" in favor of "states of concern." (Thus, should you wake up one morning and find that you've been mysteriously transported to Baghdad, you could say with double-barreled accuracy, "I am in a state of concern.") Is it possible that this State Department decision was prompted by a recent "Earthling" column that ridiculed the concept of the "rogue state"? Um, no. (The Earthling doesn't suffer from delusions of significance.) Incidentally, changing the name of these states doesn't change the point of that column. Whether you call them rogue states or states of concern, the use of them to justify building a missile-defense system makes no sense.
