In the case of the Yugoslavian wars and Serbian aggression against Bosnia, yes, NATO was good and Serbia was bad. Serbia instigated the first genocide on European soil since the Holocaust (caveat: depending on how you classify Armenia geographically) and refused to stop and back off until they were bombed. It wasnt until the bombs started falling on THEIR people and country that they finally stopped. Also, continuing to refer to Serbia as “Yugoslavia” makes me think that either you’ve no idea about what you’re talking when it comes to the Balkans, or are a Serb apologist.
