Pyonyang is a different story: there are foreign embassies that are the same as soil on those countries. Need precision bombs in the North Korean capital for that reason...

The MOAB is perfect for the Pig in the pit. Once he is out, North Korea has been liberated. North and South Korea might even unite.
