The Region of Kosovo has declared Independence from Serbia on the 17Th of February 2008, and it has been recognized by the US, UK, and France. Russia and China don't and view it as illegal. Why should we care about this one way or the other.
Well lets say that Illegal Mexican immigrants make up about 90% of the California population, then decide they want to have California be an independent country under their rule. That's basically what has happened in Kosovo, with "Ethnic Albanians" being the 90% majority.
The Serbian Prime minister has stated that " As long as the Serb people exist, Kosovo will be Serbia". Russian President Vladimir Putin describes the recognition of Kosovo's unilaterally declared independence by several major world powers as "a terrible precedent," ... that "breaks up the entire system of international relations," ...which have taken "centuries to evolve"."And undoubtedly, it may entail a whole chain of unpredictable consequences to other regions in the world" and that will come back to hit the West "in the face".
This situation worries me, as I can see this situation escalating to possibly another World War. One reason for this is because the "Ethnic Albanians" are Muslim and follow the Islamic rule and Ideals, that as we all know are in complete contrast to Western Civilization. Russia wont allow Kosovo to become "Independent" because that will embolden The Islamic Chechen separatists in their own region, and other Islamic populations throughout the World. So it wouldn't surprise me to see Russian Tanks rolling into the Kosovo Region if something isn't settled there soon.
