Among many other additional assignments, he was the Secretary-General's Personal Representative for the war in the former Yugoslavia. He also supervised the Cambodian peace negotiations and subsequent elections in 1993. Despite his successes there, he was strongly criticized for his subsequent role in the Balkans, particularly for failing to enforce the safety of civilians in a number of safe zones,[2] such as Goražde,[3] and his inability to prevent the genocide in Srebrenica.[4]
