As for Kim Jong-un, first of all, he tried to kill his half brother in 2012, and according to South Koreans, the half brother, Kim Jong-nam actually wrote a letter to Kim Jong-un pleading with him not to do that anymore.

I don`t think it`s crazy to think Kim Jong-un would use his weapons or certainly to use the weapons to try to get his, get his neighbors to do something they don`t want to do. I mean, he is not above blackmail.

There`s no end to the brutality of this regime, but it`s pretty clear this Kim Jong-un is not quite consolidated in power quite yet.

I think the fact that this was a essentially a person under [China] protection and the North Koreans went and assassinated [Kim Jong-nam], this made be the straw that really does it. And as you know, just a couple of weeks ago, the Chinese stopped all coal imports from North Korea.So there are signs that are getting serious. I guess from the policy perspective from the U.S., I mean, we got to decide what`s important to us with China?

That whole country, Malaysia has a history of telling other countries back off, we`ll do our business. They`re pretty stubborn bunch of people. So they will do what they have to do.

I think we`ve got to really get serious. And I`d put it right up there, the next four years, we are gonna get a deliverable nuclear weapon. And what is our president [Donald Trump] going to say that he did about it?
