If we had strangled the regime in Pyongyang through effective sanctions from 2002 to the present (
they would be near collapse or coup d'etat by now and this was the course Bush originally and quite correctly took before going Chamberlain on us) instead of having returned to the Clinton/Albright mode and APPEASED them and having breathed new life into them so they could continue their national policy and trajectory of nuke development and missile range modications,
we would not have to pour so much into defending Japan from North Korea through US forces in Japan.Faulty, failed foreign policy has a direct bearing on our having to stay overextended and funnelling so much into overseas military operations to protect from rogue regimes we should have long ago toppled, not "negotiated with".
