It's important that we keep our priorities straight. And we believe that the first priority is the defeat of ISIS. That by defeating ISIS and removing their caliphate from their control, we've now eliminated at least or minimized a particular threat not just to the United States, but to the whole stability in the region.

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.

People who speak up for freedom in regimes that are oppressive are often a threat.

President Xi Jinping clearly understands, and I think agrees, that the situation in North Korea has intensified and has reached a certain level of threat that action has to be taken. And, indeed, the Chinese, even themselves, have said that they do not believe the conditions are right to engage in discussions with the government in Pyongyang. And so what I think we're hopeful is that we can work together with the Chinese to change the conditions in the minds of the DPRK leadership.

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.

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.
