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.

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.

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 relationship between the USA and Russia is too important. And it's too important to not find a way to move forward.

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 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.

Obviously, the United States' own founding principles are self-determination. And I think what the United States and our allies want to do is to enable the Syrian people to make that determination. You know, we've seen what violent regime change looks like in Libya and - and the kind of chaos that can be unleashed.
