I've taken a pretty strong "intervention never justified' stance, but I admittedly know little about the balkans, and if intervention ever were justified it would be in the case of genocide. I've heard Chomsky and Parenti called genocide deniers and justify the bombing because Serbia was doing that genocide. It sounds like every anti-communist smear ever created, but I know there weren't really any "good guys" here
It really wasn't and caused a much bigger humanitarian crisis. Romani and other ethnic minorities were simultaneously targeted by KLA or whatever roaming gangs, while if they tried to escape the refugee corridors were only really open to kosavar albanians which meant they had to identify as if they wanted aid.
Coincidentally all that former SFRY industry got bombed into the stone age while western owned factories escaped that. :shrug-outta-hecks:
