While Kosovo's Serbs are preparing to flee once Kosovo declares independence, the "peacekeepers" in Kosovo prepare to enforce Albanian rule in Kosovo's northern tip. Kosovo's international rulers are still devided but if they push through this will mean the de facto ethnic cleansing of Kosovo's north tip. It doesn't help that the soldiers involved are Germans and Americans - two nations with whom Serbs have some bad memories.
Kosovo's Albanians have had 8 years to prove that they can rule their Serb minority in decent way. They have convincingly proven that they can not. I believe that the UN should draw the conclusion from this and cede the rule of Kosovo's north tip to Serbia. A nice side effect would be that the potential for conflict if Kosovo declares independence would be much reduced.
