I agree. Do you think Kim Jong Mentally Il will listen to us. Unfortunately we can't strike N. Korea at this time, and he knows it. So we wind up playing these BS games.
I don't think, barring clear indications of imminent attack by DPRK anyway, that we would ever start a war with DPRK. The risks are huge for the US and much larger for ROK and Japan. Who is going to call removing the government of DPRK a victory if one or more major civilian centers in ROK or Japan is nuked? (I know, some here will, but the real consequences of that for geopolitics and the world economy could be huge)
