Contain your bliss: We have an extra Between the Covers podcast this week. It’s with Ron Rosenbaum, author of How the End Begins: The Road to a Nuclear World War III. We discuss whether the threat of nuclear war is greater than the threat of nuclear terrorism, the problem of Iran, and whether we should all be sending “thank you” notes to George W. Bush right now for his role in getting Libya to abandon its pursuit of weapons of mass destruction.
