None of which is the credit of the NATO air campaign. Kosovo was already lost before NATO got involved. The Serbs were just evacuating its people and doing some "clean up" (read: ethnic cleansing). They finished their objectives despite the NATO air campaign and withdrew to Serbia in good order and with minimal losses.
Macedonia left peacefully, and has nothing to do with the NATO campaign.
Milosevic got caught trying to fix the 2000 elections (two years after the NATO air campaign). After a civil uprising he chose to step down. Later the new Serbian government turned him over to Den Haag for crimes he allegedly committed during the Bosnian civil war (not Kosovo).
What did the NATO air campaign actually accomplish? I mean, besides bombing a refugee column (red tractor looks like an APC?
), fire missiles into neighboring countries, destroy bridges in Belgrade, and spectacularly bomb the Chinese embassy?
Nothing.
Oh yes the NATO losses were minimal, and that is the only good thing about that whole sordid mess. Luckily none of our planes got shot down, but they might as well have been for all the good they did.
