Diane, the US is warning North Korea not to try another nuclear test, saying it would be a mistake and needlessly provocative, but those warnings seem only to provoke the new young leader even more. 

If there was any hope that Kim Jong Eun would be less threatening and dangerous than his late father, those hopes are now dashed. The twenty-something leader appears to relish his new role, now directly challenging the United States.

The reclusive nation warning the world that they will soon test a nuclear weapon, long-range rockets, one after another, today vowing that the target of its missiles and nuclear aggression, America, their sworn enemy. 

揌e抯 trying to show that he can抰 be pushed around.?

Tonight, deep inside the isolated nation, there are signs that the nuclear test is being ready. North Korea first tested a nuclear bomb in 2006. Diane, Soya was inside North Korea. Days after that test, the only western journalist meeting with a North抯 nuclear negotiators, who asserted their country抯 right to test. 

Now it抯 believed the secretive regime has a nuclear arsenal of as many as 12 weapons, and powerful ones. The last test in 2009 revealed the bomb about half its powerful as the one that destroyed Hiroshima. Model shows such a bomb could level an area roughly about the size of, say, lower Manhattan. So how big a threat is North Korea? It抯 believed their missiles can travel about 6,000 miles at best, but capable of hitting Hawaii. But what they are lacking? And this is critical. Is the ability to make a nuclear weapon small enough to be placed atop a missile and launched at an enemy? It抯 believed North Korea is still many years away from being able to do that. Still as today shows, a nation which proudly hangs anti-American posters such as this while struggling to feed its own people is working every day to become an even greater threat.

This is one of the very serious challenges that the next Secretary of State will have to face, and coincidentally, the nominee for that job, Senator John Kerry was on Capitol Hill today for his confirmation hearings.

揅hina is cooperating with us now on the run. I think there might be more we can perhaps do with respect to North Korea. There could be more we could do in other parts of the Far East.?
