The KLA problem, is in my opinion just beginning.
Really? The ANA, UCPMB, and KLA itself have all been undercut by local political changes - the Nationalist forces they were opposing have now stolen a plank from their platform in calling for ethnic partitions of both Macedonia and Kosovo.
While I doubt we've heard the last of the KLA, they're not the force they were in 1999, as they require the presence of an oppressive regime in order to be attractive to the constituents. I think they'll fade back into the obscurity from whence they came.
