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.

It's important to understand the policy of the U.S. towards North Korea is to deny North Korea possession of a nuclear weapon and the ability to deliver that weapon. Our strategy has been to undertake this peaceful pressure campaign we call it enabled by the four no's.The four no's being that we do not seek regime change, a regime collapse, an accelerated reunification of the peninsula, and we do not seek a reason to send our forces north of the demilitarized zone.

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.

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.

Just remember that a pat on the back is only 18 inches from a kick in the behind.

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.

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.
