Kosovo independence IS illigal, because it is opposite to the 1244 Resolution of Security Coucil, which recognizes Kosovo as an integral part of Serbia.

By the way, Kosovo has been Serbian for almost a millenium, it is the cradle of Serbian state, religion, culture, education, everything that defines a nation.

Ask yourself why the Americans did not go to the UN, but instead persuaded the "Kosovo government" to declare independce by themselves? Because they knew they would face Russian and Chinese VETO, and because they knew that it is against the basic principles of the UN.

You cannot grant independence to a minority by allowing secession from a sovereign state! Read some international law, if you are not that stupid.
