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.

we are dealing with a return to what might be a far more normal relationship between the West and Russia. Russia is what it is that we see. It's not dressed up in its birthday costume. It is what it is. It regards its national interests as important enough to fight for. And the difference on the whole Ukraine situation is that the Russians are prepared to fight for their position on Ukraine, and the West is not.

If anything good is going to emerge out of this, it's going to be the result of an acceptable modus vivendi between Ukraine and Russia. The two of them will have to get together at some point. It is going to be a result that many people in the West will not like, because Russia, as the bigger power, is going to get the better of the deal. So, a lot of people will say, that's appeasement. That's this - that - it's reality.

U.S. Constitution declares rather unambiguously that Congress has the responsibility to “declare war.

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?

Every nation at the end of the day must fend for itself. Sometimes, it needs help. And Ukraine deserves all the help in the world.

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.
