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.

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.

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.

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'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.

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.
