"A bully with a brilliant mind, a sharp tongue and great dexterity in exercising his impressive skills of persuasion" - this is how Radovan Karadzic was described by Professor Robert Donia, whose book "Radovan Karadzic: Architect of the Bosnian Genocide" was published end of September, days before the trial of the former Bosnian Serb leader ended.

Donia – who testified against Karadzic – believes the wartime leader of Republika Srpska, the Bosnian Serb entity established during the 1992-95 Bosnian war, was not a lunatic, as some claim, but an “aggressive leader,” and a “callous manipulator.”

Donia bases his assertion on almost two decades of research of the war, on documents made available to him by the prosecutors of the International Criminal Tribunal for former Yugoslavia, ICTY, based in The Hague, including intercepted conversations of wartime leaders in Bosnia before and during the conflict, as well as on media reports.

Speaking to N1, Donia expressed concern over the verdicts of the Court’s Appeals Chamber in the cases of Karadzic and former Bosnian Serb general Ratko Mladic that are expected to be passed in the next few years.
