You are wrong. The Russia do not want Gorgia back. The Russian forces do not fighting on Gorgia's land. The gorgian forces fighting for this region about 20 years. at this region 90% + Russian ppl , who want make his own republic.
Btw i think you understand how the Gorgia became "the part" of USA . Money and nothing else. And money not for the gorgian ppl, money only for goverment. USA goverment lies to own ppl , but i think they are havent choice. They are dont want Kenedy's desteny.
Actualy , Russian forces in South Ossetia by the law. And this is constitution. This constitution was ignored and betraded by Saakashvili.(not the ppl of Gorgia, just the Saakashvili and the goverment of Gorgia).
Try to find official site of South Ossetia , and read what they r telling. They r calling for help to protect them from Gorgian forces.
Use google.
