Rave review of a 1995 documentary on the Yugoslavian War called The Death of Yugoslavia.
Despite some criticism about the accuracy of translation, the series would be in my list of top ten documentaries of all time, I cannot recommend it highly enough. It unravels the mechanism of the sordid path of human conflict, from nationalism to genocide, like no other film before or since. It is the film that never was made about the holocaust.
Sounds like a candidate for True Films. All six parts are available on Google Video...start with part one.
