Looking for a unique honeymoon? Try what some Islamists are doing and take your new spouse on a bus tour of Islamic State’s newly declared caliphate. The militants run twice-weekly, money-making tours under the group’s black flag, complete with bodyguards and jihadist songs, from Syria’s Raqqa to Iraq’s Anbar. Passengers — most of whom are foreign jihadists — can hop on and off as they like. But they can’t sit where they like: Women at the back, men in front.
