The problem for us, Anderson, is that, you know, successive administration is going back to the early '90s and tried to reign in North Korean nuclear program without succeeding.

Well, for now. But there are two problems. One is the president's painted himself into something of a corner. Even if he really wanted to improve relations with Russia for whatever reason, there's so much suspicion about the relationship…

And if the United States is not prepared to stand up when that norm is violated, I don't think anyone else will and it's vitally important to the international community if we do so.

Secretary Tillerson is going to Moscow in the middle of the next week, actually, I think he should move up the trip and go as quickly as possible, and basically say to the Russians we're going to hold you accountable for of Assad's actions…

And the larger question is, up until now, we haven't seen a lot of regular order in this administration when it comes to making foreign policy.

I totally disagree. Certainly not been my experience. I've worked in government for 24 years through three administrations, two Democratic, one Republican.

If we're part of trying to take that apart, we're playing Russia's game.

You know, Anderson, it's deeply troubling both as a matter of process and a matter of substance.

I hope preserving the nuclear agreement which has been good for our security, good for the security of our allies and partners around the world.

The number one priority right now has to be continuing and succeeding in the effort against ISIL, against the Islamic State.

It's a terrific choice. He is one of the leading generals of his generation, both in the field, in the classroom he's really a leading intellectual, a thought leader when it comes to military and strategic matters.

I think General McMaster's going to have three challenges as he assumes this job.
