I do not think Syria can achieve international recognition in the future - even if they work through a successful political process, you know, the international community simply is not going to accept a Syria led by the Assad regime.

As far as I know, the line of communication between the U.S. and Russia continues to be open and the battlefield commanders are able to communicate with one another. I am aware that there have been certain public statements made out of Moscow.

My understanding, I was not standing nearby, but my understanding is that President Xi Jinping said, "Well, no one should kill children." The Chinese have since issued their own statement on the Syria attack itself.

Obviously, the United States' own founding principles are self-determination. And I think what the United States and our allies want to do is to enable the Syrian people to make that determination. You know, we've seen what violent regime change looks like in Libya and - and the kind of chaos that can be unleashed.

I would want to be fully informed before advising the president.

It's important to understand the policy of the U.S. towards North Korea is to deny North Korea possession of a nuclear weapon and the ability to deliver that weapon. Our strategy has been to undertake this peaceful pressure campaign we call it enabled by the four no's.The four no's being that we do not seek regime change, a regime collapse, an accelerated reunification of the peninsula, and we do not seek a reason to send our forces north of the demilitarized zone.

We're hopeful that Russia will choose to play a constructive role in supporting ceasefires through their own Astana talks, but also, ultimately, through Geneva. And if we can achieve ceasefires in zones of stabilization in Syria, then I believe we will have the conditions to begin a useful political process.
