Today UN Ambassador Nikki Haley and National Security Adviser H. R. McMaster took the podium in the White House press room. They were asked about a lot of things (transcript) but one one the first issues was North Korea.

Q Thank you, General. My question is about North Korea, which is perhaps the biggest foreign policy challenge for President Trump right now. About a month ago, the President issued a threat to North Korea; he warned of “fire and fury.” And as you know, Ambassador, at the U.N. Security Council you’ve imposed tougher sanctions on North Korea. Both of these efforts do not seem to be changing their behavior. Is it time for the U.S. to change its approach to North Korea? Is that something that you’re contemplating? And, General, if you could weigh on this well. I appreciate it.

AMBASSADOR HALEY: I think what was really important with North Korea was that we try and push through as many diplomatic options as we have. If you look at the resolutions that have passed in the last month, the two of them, they cut 30 percent of the oil. They banned all the laborers. They banned 90 percent of the exports. They banned joint ventures. We’ve basically taken and, in the words of North Korea, we have strangled their economic situation at this point. That’s going to take a little bit of time, but it has already started to take effect.
What we are seeing is they continue to be provocative, they continue to be reckless. And at that point, there’s not a whole lot the Security Council is going to be able to do from here when you’ve cut 90 percent of the trade and 30 percent of the oil.

So, having said that, I have no problem kicking it to General Mattis, because I think he has plenty of options.

Q General, can you weigh on that too?

GENERAL MCMASTER: I’d just emphasize the point that Ambassador Haley made. These sanctions are just now taking effect. What’s really important is rigorous enforcement of those sanctions so that we can really let the economic actions and diplomacy progress as best we can. But I think we ought to make clear what’s different about this approach is, is that we’re out of time, right? As Ambassador Haley said before, we’ve been kicking the can down the road, and we’re out of road.

And so for those who have said and have been commenting about the lack of a military option, there is a military option. Now, it’s not what we would prefer to do, so what we have to do is call on all nations, call on everyone to do everything we can to address this global problem short of war.
