From Cpt. Charles link:

Reuters reports Russian Foreign Minister Lavrov says he is “receiving reports of ethnic cleansing in villages of South Ossetia” as violence escalates in the breakaway province.

Whether or not it’s true that ethnic cleansing is taking place, these are the kind of coded messages that make me worry this might get bigger. Claiming that “ethnic cleansing” is taking place is, according to us and our own precedent, clear justification for armed intervention.
