But how are they any different from the KLA?"
There may be some difference in ideology, but they both were/are terrorist organizations. The difference was that the US backed and armed the KLA under Clinton and assisted them in fighting the Serbs. The US backing of the KLA and support for the succession of Kosovo is a precedent that will be used by other groups seeking independence - no matter how many times the US says Kosovo is not a precedent.
Muslims killing Muslims, how existential.
Apologies to Geico.
