When President Obama in 2011 used military power against the Qaddafi regime in Libya, he did not even notify Congress. A few in Congress mumbled, but did nothing.

But there are realities governing what they can do. And Ukraine cannot live with the false image that somehow or another the West will come and rescue her. It's not going to happen.

Well, we have got to understand, for example, Russia is an orthodox Christian nation. So is Ukraine. That happened in 988 in Crimea, a place called Kievan Rus, which was the Russia around Kiev at that time. It's 1,000 years ago, but, to a Russian, it's yesterday.

We had in the West a very romantic vision of Russia back in 1991, when the Soviet Union died and whatever is Russia began to emerge. And we began to think of it as a democracy. We're going to bring it into the West. All is going to be wonderful. That was never in the cards.

Russia can never be an empire unless it is in control of Ukraine.

Putin is a despot, and he's a very good despot. And he will see things in a narrow way. What is good for Russia? That is what he will do. If that's represented by a move toward the Baltic, that would be very dangerous, but he would do it, on the assumption that he would ask himself the question: I am prepared to fight for Estonia. Is the United States? Is Germany? Is Britain, France?

Vladimir Putin is a Russian czar. He's kind of a mix of Peter the Great and Stalin. He's got both in his veins. And he looks out first and foremost for the national security interests of Russia. He accepts that, in Eastern Europe, that is a Russian backyard, that is a Russian sphere of influence. Ukraine lives most uncomfortably and unhappily in a Russian backyard.
