Direct excerpt from an NYT article that discusses the possibility of a Russian military intervention in Eastern Ukraine.
Logical flip of this argument seems to suggest that that "Western leaders and analysts" are themselves quite comfortable with the inevitability of "extensive deaths of pro-Russian civilians" as a result of the current offensive by Kiev, with the only drawback being that it could "taunt" the rash Putin into sending his military to east Ukraine.
Meanwhile in the same NYT dispatch, "officials in Kiev say the militias and the army coordinate their actions, but the militias, which count about 7,000 fighters, are angry and, at times, uncontrollable. One known as Azov, which took over the village of Marinka, flies a neo-Nazi symbol resembling a Swastika as its flag."
I guess the surviving "pro-Russian civilians" will know that democracy and freedom are at hand when they see an "angry and, at times, uncontrollable" militia triumphantly enter their towns waiving flags with a "neo-Nazi symbol resembling a Swastika."
It is precisely at that point when the "pro-Russian civilians" will surely fall on their knees and thank their luck stars that Moscow didn't intervene with its army.
