My column this weekend is about the fact that President Obama is not the only one in Washington in search of a strategy for confronting the Islamic State terrorist group. In reading it through this morning, I was chagrined to see that I had located Libya to the east of Syria when, of course, it lies southwest across the Mediterranean Sea. I regret the error — not that it hurt anyone, but it’s very poor form to get simple things wrong while poking fun at other people’s confusion.
