A NATO-facilitated ceasefire between the KLA and Yugoslav forces was signed on 15 October 1998, but both sides broke it two months later and fighting resumed. When the killing of 45 Kosovar Albanians in the Račak massacre was reported in January 1999, NATO decided that the conflict could only be settled by introducing a military peacekeeping force to forcibly restrain the two sides.[50] Yugoslavia refused to sign the Rambouillet Accords, which among other things called for 30,000 NATO peacekeeping troops in Kosovo; an unhindered right of passage for NATO troops on Yugoslav territory; immunity for NATO and its agents to Yugoslav law; and the right to use local roads, ports, railways, and airports without payment and requisition public facilities for its use free of cost.[51][35] NATO then prepared to install the peacekeepers by force, using this refusal to justify the bombings.
It took years of fighting, but eventually both sides' refusal to sign a ceasefire was used as justification for NATO to neutralize the military forces in the region.
Oh, I see. I thought you meant they gave Milosevic a specific 6-month deadline or something.
If this was a conflict pretty much anywhere else, I think it would have gotten the standard UN ethnic spat protocol from the get-go. Instead, we're at least back to the 90's in international law.
