Is Kosovo moving towards ‘functional partition’ (or more likely dysfunctional partition)?

The nub of the international problem in Kosovo is that on the one hand the EU/US claim to rule out on principle partition on ‘ethnic’ lines, while on the other they claim that the independence of Kosovo is not in fact such an ethnic partition of Serbia, when obviously it is.

Or is the argument rather that former Yugoslavia should be allowed to break up along the lines demarcated by its internal Titoist borders on some sort of idea of self-determination for the dominant local community?

If so, why not allow Serbia to make a measured case for the claim that (a) the borders of the communist Autonomous Provinces were ‘different’, and/or (b) that where Kosovo is concerned those borders should be tweaked in the interests of achieving some higher substantive fairness – and a settlement everyone can grudgingly accept?

Whatever one thinks about the myriad rights and wrongs of all this, is a Final Result which appears to give a degree of self-determination to every ethnic community in former Yugoslavia except the largest group (ie Serbs) self-evidently … wise?
