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.

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.

I've made my own comments as to our vales as well in a speech I gave to the State Department.

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.

I don't believe anyone doubts the American people's values or the commitment of the American government or the government's agencies to advancing those values and defending those values.

We are making tremendous progress that ISIS really does present to the homeland and to other homelands of allies around the world.
