I'd recommend reading my post again. I was saying the former Yugoslav states in the Balkans are much smaller economically and power projection wise than Greece, Russia, Türkiye, Romania, and Germany - all major players within the Balkans economically and politically.
Smaller countries have less weight, sure, what are you saying exactly? Nobody but Yugoslavs (or more precisely Serbs) themselves broke their state down, they were not forced into genocide and break up.
Had they chosen not to sperg out, who knows how well Yugoslavia would have done.
