I find the situation so mind-boggling. The Russians are lying so blatantly and their objective of destroying Georgia is so obvious, and yet the "international community" has stayed basically silent.
Well, smaller powers don't want to piss off Russia because they have one hell of a big army (and huge natural ressources). Major powers don't want to piss off Russia because they've got nukes. One could try to argue that Georgia has helped out the United States militarily in Iraq, so it's now the United States' turn to help out Georgia militarily in South Ossetia. But nobody wants to see this thing going nuclear.
As long as you've got nukes and a million soldiers you are free to do whatever you like... at least in your "sphere of influence". Nothing seems to have changed in that respect. Russia has proven that now. So, in the end Western politicians are limited to publicly expressing their "concern" over the situation.
