I think your basic misunderstanding is that people over yonder identify primarily with their ethnic group, not with their nation, not even with their religion. It's a bit of a stretch to really get your mind around that if you've never been exposed to such a mentality. So an Albanian, whether he is living in Kosovo, Serbia, Albania, Croatia or anywhere else, has his stakes with Albania. And I don't mean to pick of them, all sides have the same attitude. Do you think a Serb living in Kosovo considers himself a Kosovar or a Serb? Do you think Bosnian Serbs salute the Bosnian flag, or the Serbian one? Which may be in large part what is to blame for the splintering of Yugoslavia, because people back the interest of their ethnic group over their nation, which is just the place where your ass happens to parked for the moment.
This may seem groteque or foreign to you, but that's the way it is. To throw out a random example, some portion of Jews living in America would back Israel's interests over America's. Some wouldn't, because they identify primarily with their nation, not their ehtnicity. But if you could pretty safely assume that all Jews living in America would back Israel over America, which is what you can more or less assume in any part of the ex-YU, then asking them to vote on whether the US should open talks with Iran, even if this might be potentially beneficial for the US, would be a bit absurd. Divided loyalties and all that. So if you're an Albanian, and you get to vote on whether your regional enemy is going to be weakened, yes or no, I don't believe I'm being xenophobic if I roll my eyes when you vote yes.
