Calling it a 'special case' won't stop others from trying to follow its independence example.
"Kosovo is a special case," says its declaration of independence, going on to insist (hear the advisor's whisper again) that it is not a precedent. But the 68 other members of UNPO are special cases too. Kosovo's declaration of dependent independence is the least-worst way forward, but don't let us pretend that it's not a precedent. Both statements are true: Kosovo is unique, and there will be more Kosovos.
