I still think that after the Gulf War people's view of bombing became all about accurate strikes rather than B-52s. Would be an interesting trick to demonise them to the point where just leveling Belgrade is a-okay to the average citizen at that point, kind of hard to keep that quiet.
For threats of that kind,I rather like Oakley threatening Aidid in Somalia (IIRC) - in that case, wouldn't be a problem as it was a portion of the city and no one cares for Somali dead.
