This is John Batchel, speaking with Greg Scarlato, the president of the Committee for Human Rights

in North Korea, about Kim Jong-un raising his alarms again about nuclear weapons. The question is,

is Kim Jong-un good at this? Is he necessary to the regimes that need the arsenal tapped, that would be Russia especially,

or is something happened that makes him so aggressive? Greg's answer is comprehensive.

The grandson and the son may be superior to his patrimony. Here's Greg. More of this tonight. No, I don't think you're getting too far ahead,

John. I think that Kim Jong-un, you know, there was talk when he took over North Korea.

As a very young man, age 27, that he knew the West and he would be a reformer. No, he was

picked, not because he was a reformer, but because he was the one son

most likely to follow in the father's footsteps. That said, the fact that he studied in Bern,

Switzerland, the fact that he understands the West a little bit also means that he's a better manager.

And he has managed weapons production, diplomatic relations as well, better than the father,

even better than the grandfather.
