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 never wanted all of Ukraine. He wanted for historical purposes to take Crimea. He did. Then he wanted a part of Ukraine that he could always use to advance Russian interests. And he is now at a point where nobody in the West is shouting, hey, stop. Give us back Crimea. It's all accepted. And so he has won.

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?

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.
