"What a load of commie bunk!"
This is the medias speculation because the DOD is not telling the lousy, pinko-commie-scum, newsbums anything that would jeopardize this mision. MSNBC had to generate some kind of pathetic story like this to look like they might know something.
They sound kind of large for this to work very well. A nice ground penetrating nuke delievered to a major entrance would probably do the job though. Repeat as necessary.
