But a new investigation of the mass of evidence documenting the siege suggests much wider involvement in the events leading to the fall of Srebrenica.
Declassified cables, exclusive interviews and testimony to the tribunal show that the British, American and French governments accepted that Srebrenica and two other UN-protected safe areas were "untenable" long before Mladic took the town, and were ready to cede Srebrenica to the Serbs in pursuit of a map acceptable to the Serbian President, Slobodan Milosevic, for peace at any price.
But as they considered granting Srebrenica to the Serbs, Western powers were also aware, or should have been, of the Bosnian Serb military "Directive 7" ordering the "permanent removal" of Bosnian Muslims from the safe areas.
They also knew Mladic had told the Bosnian Serb assembly, "My concern is to have them vanish completely", and that Karadzic pledged "blood up to the knees" if his army took Srebrenica.
Robert Frasure, a US diplomat working as an international representative, reported to Washington that Milosevic would not accept a peace map unless the safe areas were ceded to the Serbs. His boss, Anthony Lake, the US national security adviser, favoured a revised map that ceded Srebrenica, and the US policy-making Principals Committee urged that UN troops "pull back from vulnerable positions" - ergo, the safe areas.
France and Britain agreed, with UK Defence Secretary Sir Malcolm Rifkind arguing that the safe areas were "untenable", as defended in 1995. As Mladic's troops advanced on Srebrenica, the West failed to heed warnings of the town's imminent fall. Once it had, says General Van der Wind of the Dutch Defence Ministry, the UN provided 30,000 litres of petrol, used by the Serbs to drive their quarry to the killing fields.
As the killing hit full throttle, top Western negotiators met Mladic and Milosevic but did not raise the issue of mass murder, even though unclassified US cables show that the CIA was watching the killing fields almost "live" from satellite planes.
