Jon Stewart's Daily Show is compulsive viewing here - in the UK we get it a day late, but what the hell. Despite the humourous banter, many of the nightly interview slots these days cover serious ground. This clip, from a week or so ago, is one such. Whilst conversing with the author of a new book, "The Shia Revival", host Stewart hits upon his own plan for solving problems in the Middle East. It also makes a good deal of sense.
