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

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 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 increase in the greenhouse gas concentrations in the atmosphere are having an effect. Our ability to predict that effect is very limited.

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.

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

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.
