Georgia is an orthodox Christian nation and the Russian orthodox church recognizes Abkhazia and South Ossetia as part of the Georgian Orthodox jurisdiction. Satanic Russia pissed all over their own Christian religion by invading Georgia and murdering their orthodox Christian brothers. Evil Russia even sent jihadist muslim Chechens in the red army to massacre and exterminate Orthodox Christian Georgians.
If you stand with anti-Christian fascist Russia, the Russian Communist Party, and the inhuman svage Chechen monsters who prey on Christians, then you stand with the enemies of humanity and of Christ.
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.
