Actually, according to some counter-intelligence sources in YU at the time, Milosevic offered the US entry into NATO as early as 1990. This offer was refused.

Political theories as to who planned it, how and why are abundant. Books have been written on the issue and it has also been debated on ET on a number of occasions.

No, it clearly wasn't a "smooth operation" and numerous contingency plans were certainly worked out and implemented as the play unfolded. But to anyone who closely follows the YU wars of "independence" it is more than clear that Germany, the Vatican and later the United States were heavily involved - not as peace makers but as self-serving antagonists.

Once this belligerent outside intervention (that started in the 80's) is established, the question that springs to mind is: was the Bosnian Serb leadership the internal aggressor or the international victim? The same question is pertinent for Slobodan Milosevic.
