You make it sound like Ossetians were leftovers from the golden horde or some such. Near as I can tell from reading, they appear to be racially Caucasian, ethnically of Iranian and Scythian descent, they speak an Indo-European language, they've been where they are essentially forever, and they've been part of Russia one way or another since around 1801 at the latest.
Aside from that, given the history of the conflicts in the Balkans over the last 20 years, there is basically no way for anybody to trust American or NATO motives in any such conflict.
Vlad Putin was head of the renamed KGB and he laments the collapse of the EVIL EMPIRE. Putin's father was NKVD and his grandfather was Lenin's cook! Putin was fed Bolshevism along with his mother's milk!
Given the history of the genocidal Soviet Bolshevism Putin served all his life and has never denounced but has only defended, only a fool would ever trust the motives of such neo-soviet revanchists.
If you disapprove of what NATO did in Kosovo, then why do you approve of Russia doing the very same thing to Georgia? Isn't that hypocritical?
