Looking back in history, it was incredibly difficult for MacArthur to aid South Korea in the early stages. I would guess that it was easier for him to transport troops there from Japan than it is for us to transport troops to Georgia. By the time we get there, Russia will likely have overrun them. We could try to liberate Georgia, but that would be hell— especially against a nation like Russia. We could weaken Russia with bombing runs. But we'll need ground forces to win.
Considering that we are already fighting a war on terror with our intelligence agencies stretched to the limit, I would say the temptation to shluff this will be great.
Then there's another problem— would the people support a war? If not, it will be difficult to get funding. Photographs of dead/injured civilians would need to flood the news.
I think some airpower from Incerlink Turkey would be pretty helpful. We can’t sit back and let Russia just overrun Georgia. 150 tanks in a column up a road is a pretty inviting target.
