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 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.

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.

We express America's values from the State Department. We represent the American people. We represent America's values, our commitment to freedom, our commitment to equal treatment to people the world over. And that message has never changed.

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

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.

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