What's the Role of NATO in the Yukoslavian War?

Nato was created to combat a soviet threat, and that's a country that doesn't exist any more. So from a western perspective, we tend to think of nato as purely defensive. But if you want to make the russian political elite really annoyed, you talk about yuguslavia and you talk about the independence of kosavo. What makes them a little bit crazy is this idea that it's up to nato, rather than the u. N to redraw these boundari.
