The latest issue of Dabiq hit magazine stands this week. Well, not all magazine stands, because Dabiq is published by ISIS. The glossy, English-language quarterly features some typical magazine fare, but with a Jihadi slant. For instance, there’s an advice column for widows of fighters who died for the ISIS cause.
