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'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.

People who speak up for freedom in regimes that are oppressive are often a threat.

There have been over a million wells hydraulically fractured in the history of the industry, and there is not one, not one, reported case of a freshwater aquifer having ever been contaminated from hydraulic fracturing. Not one.

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.

I think the Russians need to think more carefully about the commitment they made under the chemical weapons agreements to be the guarantor that these weapons would be seized, they would be removed, they would be destroyed. And since they are Bashar al-Assad's ally, they would have the closest insight as to the compliance.

We've seen what violent regime change looks like in Libya and the kind of chaos that can be unleashed. And, indeed, the kind of misery that it enacts on its own people.

Once the ISIS threat has been reduced or eliminated, I think we can turn our attention directly to stabilizing the situation in Syria. We're hopeful that we can prevent a continuation of the civil war and that we can bring the parties to the table to begin the process of political discussions.

I feel it's important that in advising the president, if confirmed, that I deal with facts, that I deal with sufficient information. Which means having access to all information.

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.

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

I think there's a shared view and no disagreement as to how dangerous the situation in North Korea has become. I think even China is beginning to recognize that this presents a threat to China's interests as well.

I think continued actions by Bashar al-Assad clearly call into any question of him expecting to have any legitimacy to continue as the leader of Syria. With each of those actions, like attack with conventional weapons, barrel bombs and block humanitarian aid he really undermines his own legitimacy.

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

Russia and the USA are two largest nuclear powers in the world it's a really important relationship. How do we start making this work? How do we live with one another? How do we work with one another? We simply have to find a way to go forward.

People who speak up for freedom in regimes that are repressive are often at threat.
