As for S. Korea, it may pull out of joint industrial complex in N. Korea's Kae-sung, where S. Korean companies manufacture products with N. Korean employees. It was set up more than 10 years ago, when S. Korean government was run by those who favor appeasement of N. Korea. Due to the danger of hostage crisis, when S. Korea attempts to pull out, and other factors, it has been allowed to operate until now, but that could change. Another development could be that S. Korea will approve the deployment of THAAD missile defense system. Due to vehement opposition by Chinese, it has been delayed, but this could also proceed.
General public are pretty upset over N. Korean belligerence and China's complicity. Survey shows that a majority of them favor S. Korea's own nukes. I don't think that it is politically possible, though.
I have favor putting in THAAD as well additional U.S. forces, and more Hardware on the Peninsula.
Now, the question is...what exactly WAS that ‘projectile’ they supposedly orbited? Is it really a satellite, or something much more sinister?
Will it’s orbit ever bring it over, say, the central US?
