The fact on the ground is that northern part of Kosovo is integrated to Serbia like it always has been, as well those pats south of Ibar river, which are not ethnically cleansed by Kosovo Albanians. Between ethnic groups a huge operation of international community is going on with its foggy ideas.
From my viewpoint the only way to get sustainable solution to Kosovo is through real negotiations between local stakeholders. To get start of real talks US should freeze or withdraw its recognition of Kosovo UDI; otherwise it takes too long time for Kosovo Albanians to find out that some negotiated outcome – be it cantonization, partition or whatever agreed - could be better than status quo. (About possible solutions “Dividing Kosovo – a pragmatic solution to frozen conflict” and “Cantonisation – a middle course for separatist movements” )
