To me, one of the most fascinating and terrifying aspects of the the Ukraine situation is the peed with which the revolution happened. Overnight, the government fell in Kiev and chaos ensued. I cannot imagine what it was like to be the regional and city governments, or the police or the armed forces. Do you remain loyal to the "officially elected" government, even though it seems to be no longer in power - do you take matters in your own hands locally?
Ukraine is a nation of 46 million people; it is in the heart of Europe. At least on the surface it seemed to have a mature government infrastructure. I wonder if the same thing would happen in the US if someone took out the Federal government in DC?
