Because the history books generally would say two years later, 1991, declaration of independence of Slovenia and Croatia.

Saying 1989 is a political statement, one I may or may not agree with, relating to actions Milosevic took relative to an internal Serbian matter on the statute of Kosovo. A political statement, not a statement of fact. Otherwise, why stop at 1989? We can go to 1981...that wasn't even Milosevic...or again, why stop there, we can go back to the famous 11th century or whatever that Serbian nationalists are always on about.

Again, you present a political statement as a fact.
