In my view, [Vladimir] Putin despises the West in general and the United States in particular, both for who we are, our liberal values, and for what we`ve done, which is to take down the Soviet Empire.

Two World Wars are sufficient and we are the ones who supported this notion of a united Europe, so there would never be another set of civil wars in Europe again, ever. That was a fabulous success. It was so fabulous that people now take it for granted.

America's security and prosperity didn't work unless other nations were also secure, and prosperous. There had to be something in it for them, so we weren't looking simply to grab territory, or widen our sphere of influence, or anything like that. We wanted to make the world a better place, and get very rich in the process.

The American tradition of foreign policy exceptionalism, our grand strategy as a nation, reaches back much further. Really at the turn - the end of the 19th century, when we achieved power a generation after the Civil War, the outlines of an American vision came into focus, and what we - it was based on two things. One, our realization that our values and our interests were the same, and that our business interests would advance as our values advanced in the world.

Sanctions are a strong and agreed element of the West's response to Russia's aggression. It is puzzling to me that there is so much skepticism about the sanctions. I don't understand it.

Republicans - Reagan but also George W. Bush - believed in freedom, and they believed in America's role. To have the governing party speak in terms of a zero-sum world, or speak in terms of America's purpose as no more than grabbing the largest share possible in the short run, goes against our foreign policy tradition that goes back to 1900, really.

America's sanctions policy remains intact, and it will remain intact until it changes, if it does, and I'm not sure it will.
