A targeted attack is eminently doable.
Im not too familiar with the tech we got today, but I assume it is possible now that they could zero in on fat boy Jung Un from sattelite when he steps outside and MOAB his ass? I wonder what would happen if we did that, would it be like cutting the strings from a puppet? Would they be confused as what to do without the “Dear leader” or does fat boy have a chain of command set up?
