The lack of recognition from some countries--say, Sweden--is purposeful as a safeguard against Albanian forays into Northern Kosovo. The EU wants to keep using the carrot and stick approach.

I don't know why though since eventually the Serbs will either split off the north or leave it altogether.

Let's face it. The international community and the Albanians have been arguing, "We can't live with Serbia." I fail to see how that logic doesn't also apply to Serbs in Kosovo.
