In Montenegro, Ljubomir Filipovic, a political scientist and former deputy mayor of Budva, said Djukic helped spread chaos and dysfunction in a country that has struggled to establish an identity since it became a sovereign nation in 2006.

“He went beyond what an ordinary honorary consul would do. He went even beyond what an official diplomat would do,” said Filipovic, who tracked Djukic’s activities as consul. “The intention was to damage the social fabric of Montenegro — and he did that.”
