> So Putin is so angry and feels threatend that he wants to overthrough Ukraine, and the answer is to make them a member of the EU? This screams like more aggressives answers from Putin. I personally expect a smaller nuclear warning shot over the ocean from Putin next week.

There is an option: attack first. If Russian nuclear C&C is taken down, I doubt any of officers in the bunker would dare to launch. Even if they will, these would be uncoordinated launches, and nowhere near the size of a coordinated attack.
