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

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.

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.

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.

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.
