I would want to be fully informed before advising the president.

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.

The military progress both in Syria and in Iraq has been remarkable since President Donald Trump's inauguration. We have continued to liberate areas. We are making tremendous progress in liberating Mosul in Iraq, working with coalition forces, we're moving to position to liberate Raqqa.

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.

My understanding, I was not standing nearby, but my understanding is that President Xi Jinping said, "Well, no one should kill children." The Chinese have since issued their own statement on the Syria attack itself.

People who speak up for freedom in regimes that are repressive are often at threat.
