Ten Taepodongs taped together? Heck, I'd pay to see that, the explosion would probably be bigger than the nuclear bombs (which would probably be a dud).
True, as a denial weapon I guess it would be rather limited, but then again in the media game, you've got to just inflict as much casualties as you can and last as long as you can until the US and EU media shows enough dead bodies coming home to set in war weariness. Pictures of mushroom clouds rising up over the DMZ, particularly if it's done on North soil, would make people question the decision to head north into the DPRK.
