And, what are we going to do? The US military is tied up in Iraq and Afghanistan, and even if they weren't, getting to Georgia isn't going to be easy. The Euros don't have the balls to do anything meaningful to their largest energy supplier. So, what do you suggest? WWIII?
This is a larger part of a regional conflict that includes Chechnia. There are layers of ethnic hatred in the region that go back a long way and I find it hard to believe anyone's side of the story. This is a tragedy, but at this point the best thing to do is just to get the shooting to stop.
