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.

Our priority in Syria, really hasn't changed. I think the President Donald Trump has been quite clear. First and foremost, we must defeat ISIS.

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.

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.

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 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.

I think what we're hopeful is through this Syrian process, working with coalition members, working with the U.N., and in particular working through the Geneva process, that we can navigate a political outcome in which the Syrian people, in fact, will determine Bashar al-Assad's fate and his legitimacy.
