Why do think I've taken the attitude I have? It's because there are NO heroes in the Balkans, just varying shades of villain.
This sums it up nicely. It's not surprising, though, that Bill Clinton aligned himself with the foulest of the bunch. The Balkans are sort of what you'd get if Northern Ireland were positioned where Israel is. Continuous friction exists between two Christian groups and the Muslims are causing trouble as well - for everybody. I know... this is an oversimplification. The analogy works for me, though.
Ever since the Ottoman Turks relinquished that territory, this kettle o' fish has existed. Orthodox Christians who secretly practiced their faith hated the Muslims (Albanians, etc.) because they abandoned Chritianity and converted to Islam while under Turk rule. The Orthodox Christians (mostly Serbs) also nursed a grudge against the Croats (Christians in areas not occupied and by then primarily Catholic) for leaving them at the mercy of the Turks for so long. It was and remains an unmitigated mess with no foreseeable solution.
Any possible improvement there would've had to be carried out on a sub-rosa basis, which is pretty much what Milosovic (sp?) was doing. Yes, there were Serb atrocities - mainly in the early 1990s - but the later allegations concerning Serbs murdering Albanians and such remain the stuff of rumor and conjecture, AFAIK. Heck, such actions against Islamic extremists would be smiled upon these days - a thought that brings ol' Slobodan little comfort, I'm sure.
Perhaps "Running all the Muslims out" should be tried before resorting to your "Kill 'em All" approach. Oops, I forgot... that's already been tried and will bring grief on the wings of NATO aircraft. Still, the intrusion of Islam into an area populated by Eastern Orthodox Christians is what got this whole train a-rolling. Maybe they should be the first group invited to leave - just to see if Islam *is* the problem. If that fails, we go to your idea (Plan "B").
