Oh, we're playing the empathy game eh?
If the land was being taken by the people who actually lived there in response to a legitimate grievance then good luck to them.
If your government was trying to ethnically cleanse your ethnic group would you be happy to continue being governed by them? If Serbia was serious about hanging on to Kosovo it should have been a hell of a lot nicer to Kosovo's majority ethnic group. Instead they just tried to kill them all and now Kosovo has had the good sense to part ways. Cry me a river.
I see you're playing the empathy game too. Here are two things you may do well to understand, and that I am surprised to read that someone of your calibre apparently does not:
1) Milošević is dead.
The Serbia that this unilateral declaration of independence happened to is not the Serbia that he ran. And his government was far from being representative of all the people he governed over anyway. I suppose I should have very little sympathy for you being a British passport holder, because you must be just like that filthy war monger and war criminal Tony Blair? Or, to reflect the temporal distinction between today and when Milošević was around, I guess you must be another Thatcherite lacky arsehole, who deserves no sympathy whatsoever.
The Serbia that this has happened to is a nation that was peacefully and diplomatically trying to solve this problem, through the normal legal channels. Their current government is comprised of the same people who handed Milošević over to The Hague. They were on their way to coming to a compromise for both sides, but the powers that be were not interested in due process and jumped the gun "to bring peace to the region".
2) Kosovo Albanians may not want to be a part of Serbia, but they have never asked too politely about it and Serbs in Kosovo have received brutal treatment at the hands of the Kosovo militias, population and allies alike.
Serbs were being intimidated and driven out of their homes in Kosovo in a concerted fashion at least since the early 1980s (sure you can go way back in history to see the ebb and flow) and Milošević only came to power in 1989. These Serbs, who suffered at the hands of the Kosovo Albanians, became the followers of radical nationalists in Serbia. It is these Serbian refugees from Kosovo, as well as other parts of the former Yugoslavia, who are/were the followers of people such as Milošević.
Further, the various Albanian separatist movements were (and still are) very heavily armed, as someone with the police dad above pointed out. It was after the oh so enlightened Dayton Agreement, in 1995, that Kosovo Albanians organized into the Kosovo Liberation Army and started clashes with both the Yugoslav army and Serbian police. Again, nothing to do with due process here. They were using outright violence, sanctioned by Washington and London and the rest of NATO.
Then you must consider that, in 1999, NATO bombed the sh!t out of Serbians, and even more Serbs, about 100,000 according to the UNHCR, were thus driven from Kosovo. Estimates hover around 50-60% of the Serbian population fleeing Kosovo in the face of this violence (conveniently laying the ground work for the demographics arguments that we now see flying around).
In 2004, with UNMIK present, there was still more serious violence. And the specific catalyst here being the drive-by shooting of an 18 year old Serb called Jovica Ivić. Serbs protested against this. Albanians gathered in their thousands to greet them. Violence ensued and some 3,600 people had been made homeless by the violence, mostly Serbs. Their houses were burnt to the ground. They were shot indiscriminately. Even the peace keeping forces had people gunned down by Albanian militias. Of course, there were armed Serbs who shot back, it's never been pretty or simple. But this event was what set the ball rolling for attacks on Kosovo Serbs all over Kosovo. Their houses, churches and other cultural institutions were burned to the ground and they were either killed or chased out of the region.
There are so many other events in this whole process that I could point to for you. But this is perhaps enough to illustrate the point for now, which is basically that....
You are buying the sympathy line of downtrodden people when considering the Kosovo Albanians. But are they the only downtrodden in this story?
The downtrodden are on either side my friend. How can you possibly back just one group and not the other? And for how long must the Serbian people suffer collective punishment on behalf of a leader that they handed over to The Hague ages ago and who is no longer even alive?
