The Kosovo War has long since been forgotten by the American public.
After all, it was supposed to be over. The good guys won, the bad guys lost, and everything got settled.
The problem is that all three of those assumptions are wrong.

I remember every night in the mid or late 90's listening to the VOA and BBC World Service that Serbia, led by Slobodan Milosevic were committing the most atrocious of war crimes in Yugoslavia. Milosevic was, we were told, worse than "Hitler". Clinton was in the forefront of slanderous attacks on Milosevic blaming him for the violence in Bosnia and Kosovo, Milosevic's evil justifying the US bombing and destruction of Serbia.
