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.

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

The increase in the greenhouse gas concentrations in the atmosphere are having an effect. Our ability to predict that effect is very limited.

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 the President Donald Trump was quite clear in his statement that he made to the American people that Syria's continued violations of U.N. resolutions and previous agreements that Syria had entered into regarding the Chemical Weapons Accord would no longer be tolerated. I think we have stood by and watched multiple weapon - chemical weapons attacks by the Syrian regime under the leadership of Bashar al-Assad.

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.
