Well, everything else there will result in a bloodbath, if not now, then a bit later. One could argue that if both sides mutually exterminate each other to the last man, the rest of mankind would sigh with relief [true, as both sides are rather unpleasant], but one is supposed to have a humanitarian inclination these days.
But Serbia has probably been America's one and only staunch defender in the area, even through WW2.. One of the few places American Soldiers were given aid and kept safe from the Nazis..
Additionally, the West has become a bit more aware of how dangerous Islam and Islamic nations are since the fall of the USSR...
Can we (the west) afford to create another Islamic nation in the heart of Eastern Europe?
Kosovo has surely been no "multicultural paradise"..
The albanians are just as bloodthirsty as ever, and I can see in retrospect that Serbia may have handled the situation harshly, but it looks like they were essentially correct..
An Albanian Kosovo is a future threat..
I'm not sure we can even afford the creation of Bosnia, which has a largely Islamic population..
The west, (both the EU and US) should consider carefully what they are doing..
There is a very good chance that both Bosnia and Kosovo will end up being akin to a "cancer" in the midst of Europe..
It might be best to deal with it now, rather than later..
