Get Russia to repeat that their invasion is to protect the Russian enclaves. Then mobilize a massive humanitarian U.N. or USA response. Locate large U.N. or USA personel in Georgia as quickly as possible.
Then wait for a Russian tank or aircraft to come to near and shoot and destroy it. Then inform Putin and company that you will not tolerate any threats to humanitarian personel. If any further aggression occurs warn the Russians to instruct their personel to stap aside from their military hardware as it will be destroyed in 1 hours. Then use US air power to destroy all tanks in Georgia.
The Russian hardware is not sufficient to stop any of this from happening. They will not go nuclear as we can match them on this. The sooner the better as you do not want Russia developing feelings of attachment. We need to strike before they think they own Georgia.
