Jović was a close ally and advisor of Serbian official Slobodan Milošević and helped Milošević attain power during the anti-bureaucratic revolution. He served as chairman of the presidency of Yugoslavia from May 1990 to May 1991. In his book, Poslednji dani SFRJ, Joviċ describes how in late June 1990, following the electoral victory in Slovenia and Croatia of pro-independence forces, he proposed to Milošević and federal defense ministerVeljko Kadijević that they "throw Slovenia and Croatia out of Yugoslavia" through the use of force, while retaining hold of Serb-populated sections of Croatia, to which Milošević agreed. Shortly after that meeting Jović began implementing the strategy that led to the end of the federal Yugoslav state. Jović is known for helping to negotiate the Brioni Accord in early July 1991, which gave Slovenia its independence after the Ten-Day War. Near the end of his mandate in the rotating presidency, his successor, Stjepan Mesić, a Croat, was blocked from taking the presidency by four out of eight members of the presidency who thus violated the constitutional arrangement for rotation. In mid-1991, with the tensions leading to the Croatian War of Independence rising in Croatia, Jovic attempted to enact emergency powers which would effectively enable the army to take control of the country and reverse the effects of the first free democratic elections which had elected independence-advocating governments in the republics of Croatia and Slovenia. A vote of 5 out of 8 members of the Presidency was required, and Serbia had under its political control votes of Serbia, Montenegro, Vojvodina and Kosovo, and presumed that the Serb delegate representing Bosnia and Herzegovina would vote for the plan. The plan backfired when the Bosnian Serb delegate, Bogić Bogičević, refused to vote for the plan. In the 1995 BBC documentary The Death of Yugoslavia, Jović described to interviewers his perception of the events that took place that eventually resulted in the breakup of the Socialist Federal Republic of Yugoslavia and the subsequent Yugoslav Wars. During this interview, as well as in his testimony before the ICTY, Jović described the actions of the Yugoslav leadership that led up to the formation of the Bosnian Serb Army. Jović claims these actions were decided in a private discussion he held with Serbian President Milošević. According to Jović, he realized that Bosnia and Herzegovina was about to be recognized by the international community, and since Yugoslav People's Army troops were still located there at that point, their presence on Bosnian territory could have led to the FRY being accused of aggression. To avoid this, he and Milošević decided to move all JNA soldiers originating from Serbia and Montenegro back into Serbia and Montenegro, and to move all JNA soldiers originating from Bosnia and Herzegovina to Bosnia and Herzegovina. In this way, every Bosnian Serb was transferred from the Yugoslav army to what became the newly created Bosnian Serb Army. In the film, Jović revealed that Yugoslavia promised to pay all the costs, as the Bosnian Serb government could not afford the costs on its own. Jović viewed the reformist former Yugoslav Prime MinisterAnte Marković, a Bosnian Croat, as responsible for destroying the country and of being a puppet of the capitalist west. Jović, while President of Yugoslavia, commented:
The general conclusion is that Ante Marković is no longer acceptable or reliable to us. No one has any doubts in their mind any longer that he's the extended arm of the United States in terms of overthrowing anyone who ever thinks of socialism, and it is through our votes that we appointed him Prime Minister in the Assembly. He is playing the most dangerous game of treason.
Jović's conclusion on Marković's role:
He was no doubt the most active creator of the destruction of our economy, and to a large extent a significant participant in the break-up of Yugoslavia. Others, when boasted of having broken up Yugoslavia wanted to take this infamous role upon themselves but in all these respects they never came close to what Marković did, who had declared himself as the protagonist of Yugoslavia's survival.
