Looking at the entire Caucasus with respect to its geopolitical ramifications, is the biggest picture possible.
The last thing that the Russians wanted was another occupying army in a land that doesnt want them.
I have to bail on this discussion, but please it is clear that you cannot possibly know what the Russians wanted.
They dont need to go any further.
So this was all about need ?
Yes a need to bloody the nose of Saakashvili and to finally secure and annex the territory that they wanted. Georgia isn’t going to get the territory back. Even Putin and Medvedev wouldn’t be stupid enough to drag Russia into a total occupation of Georgia.
