Smartassery aside, you were definitely right in calling it back then. The war in '98 was a geographically smaller version of WWI and WWII, in some very specific ways. Both wars started when ultra-nationalists decided they should get their way, no compromises. Both wars ended with the losing party feeling humiliated. That humiliation bred a "LET'S SHOW THEM!" mentality of nationalism (starting to see a pattern?) which eventually festered and turned into downright arrogance and cockiness toward everybody else. That is exactly what is happening here and anybody who's been watching would be drunk not to see it too. The Serbs have long felt like the losing party (they lost their little empire Yugoslavia) and this is just the final straw after losing Montenegro.
The nationalistic fury has clearly been pushed over the edge into a rampaging state of chaos, and bonus fail is that we're seeing alliances start to form again, just like WWI and WWII. Tensions among the major members of the opposing alliances aren't much helped by the fact that the NATO countries, most especially the U.S., are already at odds with Serbia-backing Russia over missile defense systems being put in place in NATO member states (most notably in Ukraine, where, according to the BBC, Russia even went so far as to threaten nuclear strike).
I'm not trying to fear-monger here (although I am seriously scared out of my goddamn wits), but if people don't stop being FUCKING STUPID here in the Balkans, epic shit's gonna go down and it's not really going to be all too fun for anybody.
