The Serbs are Christian Europeans.
The Albanians were the invaders and they are Muslim.
The UN sided with the invaders.
Alot of murky water got spread back and forth about what happened, but the biggest thing is that the albanians were trying to take the country, in the name is islam, and the serbs told them to go fuck themselves. They fought, the serbs killed alot, and we got the UN in a tailspin thinking that there was mass genocide going on. Sure, the serbs killed alot, but looking at that instance in this day and age, i have to agree with the serbs.
It'd be similar to Jordan invading and taking over israel, and israel killing as many as possible to prevent a take over, then the UN stepping in and saying "no no no, bad israel, you have to let them take over"
Moral of the story, the whole area between Austria and Turkey is a fucked-to-death pile of burning shit.
