Considering how impolite the KLA was being and the history of the area, hardly something we needed to be involved in.
The Serbian government was being a pain from the beginning in Yugoslavia. Miloslevic began the whole mess, you will recall, when he put the rest of the then “republics” in a bind, by declaring the unilateral authority of the Serbian government over the others.
It was no longer a coalition of equals but Serbia uber alles. Very much a dick move.
Hence the others left, mostly in a very bloody mess, opposed by Serbian military forces.
