The South has nukes too- or at least, an umbrella agreement
If NK takes out Seoul....China may step in and warn the US and Japan to back off. China is the good guy and runs NK while Seoul is a smoldering ruin.
You, Welshman007, are Anthony Martin? How enterprising.
Kim has judged Obama and found him wanting.
He knows the UN is a paper tiger and he is pretty certain Pbama will do nothing, the time is ripe to reunite Korea.
Hey Zero!!! How’s that reaching out and understanding our enemies program working out?
Yep, they have nukes. They could probably field 6-12 low ktn. nukes on missiles. They could hit Seoul and obliterate it. Of course they have been able to do that for decades anyways. They have over 10,000 pieces of artillery in striking distance of Seoul. Seoul would be in ruins in about an hour by conventional means anyways.
But if NK nukes South Korea or Japan it's game over for them. There wouldn't be a piece of DPRK soil that wasn't radioactive by the end of the day.
Not to mention China is not going to let them go to war. If DPRK invades South Korea or uses a WMD Japan will go Nuclear themselves and then China is faced with it's most hated Neighbor having nukes and greatly shifting the balance of power in Asia.
In summary;
DPRK is not suicidal.
China is not stupid.
More then likely the North is running low on something they need, or Kim is rattling his saber to get his way with his successor with The Millitary.
This is how he gets attention and what he wants from the Party and the world at large. Nothing new here.
