Ukraine Crisis PR. Mitchell Plitnick, in Friday's Souciant.
To my eyes, a good analysis and contribution.
A useful summary of realities in Ukraine and the Crimea that some might find useful: http://www.bbc.com/news/world-europe-26387353. (The passing reference to gas reserves in the Azov and Black Seas is, perhaps, worthy of a careful note by the "follow the money" crowd.)
The general question remains: under what circumstances can the will of a regional majority to secede -- trump the will of the state to maintain union? And how are such questions to be resolved short of civil war?
