Some blogger on Georgia vs Russia. As they say, go read the whole thing. It's fairly reasonable.
This kind of thing has been an nagging concern of mine during the leftward shift in foreign policy over the past couple of years. The neocon philosophy of super aggressive militarism has been a disaster, but that doesn't mean that the best foreign policy is the one farthest away from Bush's.
For example, a lot of people are arguing that the US needs to deal with the fact that Russia is going to have a 'sphere of influence', and that there's a limited amount that we can affect that. Which is completely true. But accepting a Russian sphere of influence isn't the same as accepting Russian tanks rolling through the streets of independent nations. So many are saying that the Soviet Union is gone, we aren't fighting the Cold War anymore, but it's pretty clear that the thugocracy running Russia is still fighting a war.
