The have committed heinous crimes against some innocent Serbians. Many Albanians dislike the KLA for the way it has handled it's anger at oppression. Many wish they would have appealed to Peace Preserving countries before committing violence against a much stronger army of Serbia. They dislike the idea of the KLA recruiting new refugees saying that it's Serbia's falt their homes are flaming when in fact is Serbia's retaliation against KLA terrorism. The uncomfortable point to mention here is that it's true Kosovo legally belongs to Serbia.
All laws show that.
And it's true that the bigger better army wins, and that the way they win is gruesome. Might does not make right. And two wrongs don't make a right either. It's like me saying I protest someones actions and that person kills everyone who ever knew me, along with their family and friends. The wrong people are being punished and held accountable for things done out of their control.
