I can see why you would think that. But the "Rosetta Stone" to this, isn't really about the squabbles between the ethnicities who live there. Those were just exploitable cleavages. It is in the machinations of the outside globalist political forces who have intervened to divide up the Balkans and sell them off to the highest bidder.
The propaganda is that the ethnicities act against each other and then the West "reacts" with intervention -- when it is in fact, the other way around. We, in the West, act and then they react over there -- usually by killing each other.
One of the forces that comes to mind is Russia-which-having negotiated a pipeline deal involving Kosovo,is in no mood to re-negotiate.
