It is sad series of events, still unfolding and can only get worse for the inhabitants.
The worst part in my opinion is - the school yard "fight fight" type support provided by others to Ukrainians and then do practically nothing. There are plenty of pundits with their analysis on everything but I feel for the locals.
On that note, there is a YouTube lecture by a University of Chicago seriously smart Professors. The scariest part is - this was recorder in Sep 2015.
