OK guys stick with me, this is China testing Obama once again, think of the supposedly jet trail of the coast of CA. Also anyone who has read any Korean History along with Mao teachings knows that NK is a puppet of China, only used as a buffer. Mao used the NK regime to start the Korean war and if Kim refused he was gonna invade them. That is why the US took a big interest in this war back then, as it was also backed by the Russians.
This in my opinion is not just saber rattling, think of a few months ago when a SK naval ship was sunk killing 46 soldiers. Also NK just announced a second uranium enrichment unit.
Pb Andy may be right and lets hope thats all..but I was there for 1 yr and I can tell you in peacetime its no joke. Right now its big time serious there for out troops. I can almost guarantee weapons and real ammo has been issued at least I hope so. I honestly do believe China is behind this..read some history on the regime. Also China supplies them with everything how else can this poverty stricken nation have nuclear bombs. China is testing Obama once again and this time if he fails they might go something more drastic.
