Although very little was known about him during the 1990s, he is widely seen as the "mastermind and conductor of controlled chaos" during the large part of Yugoslav Wars.[2][2] Despite being the closest person to the President of Serbia Slobodan Milošević, with enormous impact on wartime events, he kept permanent contacts with all the factors involved in the conflict.[2] Allegedly, he was removed in 1998 from the key intelligence position due to disagreements with Mirjana Marković and the Minister of Internal Affairs Vlajko Stojiljković, as he opposed the excessive use of force in Kosovo.[3]
