1. The war's already been fought. The Serbs lost.
2. The Russians don't care enough to do anything about it other than posture before selling their erstwhile allies down the river.
3. The French overestimate their influence and capabilities. I see no reason to do the same.
At least that's the way I see things.
The Serbs will fight again for Kosovo.
As for Russia/France and the rest...always a crapshoot with such personalities. Could go any direction.
The better way to look at it is what's in it for the U.S. if Kosovo *does* become independent.
Now compare to our position if Kosovo remains quiet. Judge. Balance. Decide. Act.
Frankly, I see no reason to provoke bloodshed there. What's our gain in such a deal?
