We did not have large trade flows to and from the Balkans, our trade with Yugoslavia in 1990 amounted to half a Billion in exports and .7 Billion in imports - but that does not mean that we get to ignore them, only to react with shock and dismay when their neighbors, with whom we do have large trade flows or are encouraging towards market economies, get involved in their neighbor's internecine bloodfest and drag us in after them.
Our armed forces are currently deployed around the globe to try to keep lids on local disputes and insurrections in order to stop them from turning into regional conflagrations that we cannot ignore - I don't suppose the fighting along the border between Thailand and Myanmar is of too much interest to you either - but there we are. Go figure.
And if you believe Milosevic was merely dealing with an Islamic insurrection, then you should be able to come up with an amusing answer as to why the Serbians were cracking Albanian Catholic heads and even managed to destroy two Catholic churches as they were getting their silly little selves bombed out of Kosovo.
