Strangely enough, in the years since, a loose coalition of international leftists have taken up the conspiratorial cause of Serbian recidivists and nationalists in declaring the NATO air campaign as an act of 'imperialism,' both unjustified and illegal. I can perhaps see why younger Serbians would be reluctant to see themselves as aggressors; it is harder to understand why Western leftists would take up the cause of someone as loathsome as Slobodan Milošević purely to make an ideological point.
Furthermore, if this intervention irked the Russians, it had very little to do with questions of international law and sovereignty, and much more to do with the fact that this area has long been seen by Moscow as its personal playground (famously, one of the primary causes of WW1), and signaled a blow to their declining prestige.
Finally, I would be wholly suspicious of any comparison of Yugoslavia to the current crisis in Ukraine, as it implies some legitimacy to Moscow's patently fictional claims of 'genocide' in the separatist areas in the east. Regardless of who 'forged the world in which such a war is possible,' this particular war is purely a creation of the Kremlin's grandiose and cruel imagination.
