Two interesting and different commentaries on current events. One by a RUSI analyst 'Viewpoint: What is driving North Korea's threats?':http://www.bbc.co.uk/news/world-asia-21950069

The author notes:
....there is little reason to suspect that it will deliver on some of its other promises, at least anytime soon.

One reason for this is that a major audience for Kim Jong-un's tough talk is domestic. The young leader was promoted quickly through the ranks of the Korean People's Army by his late father, despite having done little to earn those qualifications. Standing up to North Korea's enemies will help Kim Jong-un consolidate his military and political power.
The second is by a long-time British academic expert on North Korea asks 'Could a Korean Armageddon really happen?:http://m.guardian.co.uk/commentisfre...ageddon-happen

Namely: are they serious? Do they mean it? Could a Korean Armageddon really happen? My one-word answer would be no. A wag at South Korea's defence ministry quipped earlier this month that "barking dogs don't bite".
I'd forgotten the joint venture in North Korea by a South Korean company and the author notes:
And each day dozens of South Koreans still commute from Seoul across the DMZ to supervise Northern workers at a joint venture industrial park. That is the reality on the ground. With any luck it will remain so.
In a previous article @ Kaesong this activity has never been stopped:http://m.guardian.co.uk/commentisfre...known-quantity

One wonders what China and Russia think?
