Keep going Peter. That is one of the vital interests, obviously if a US city even if on Hawaii or Alaska can be attacked by North Korea, that is a game changer. What of our ally Japan and South Korea? What of navigation on the East and South China Seas? What of our 30,000 US troops there Pete and their families, is that of vital national security interests or are those donttread's defense industry machine trying to get rich? See, I know you know this stuff Peter, what I find odd is your reluctance to voice these threats and geopolitical analyses and matrix. Why you purposefully underscore threat matrix once confused me, now I just find it odd as it's so obvious what you're doing.
That is why those previous incidents mentioned in Rolling's post above didn't uspet the US much and the potential for a North Korean nuclear strike does.
Yes...let us look at Rolling Wave's post as it needs serious editing. Sorry RW, nothing personal, but.....your premise of "just leave North Korea alone is the more reasonable and realistic approach" I must take issue with. The current struggles also not an 'excuse for a trade war with China', you almost seem to contradict your own arguments there and move towards the correct analysis. You push for market reforms in the North. That of course I hate to say will necessitate regime change. A military option where you cannot engage and be leaving NK alone at the same time. Secondly, you do mention China and the economic, diplomatic, and yes military pressure needs to come from China who is the major belligerent in this geopolitical scenario. North Korea is a threat to Japan, South Korea, the United States, navigation, free trade, and the entire Pacific Rim......and its' because China wants them to be. China....needs to be taken on full force and I do believe Trump understands that.
Well then stop guessing and answer, Peter. The answer is obviously yes. They're a real actor. Rational I cannot make that call, I do know the actor must have a Producer, a Director, a Facilitator, a Funder, someone to baby the actor, bring candy to the trailer on rainy days. Spoil the little insecure actresses.I guess you have to answer this question: is the North Korean government a rational actor or not. (I have argued several times that they were).
