Exception to this is Serbia, which seen as the culprit for the actions of Yugoslavia got RAYPED, even eastern Vojvodina became a Autonomous state administered exclusively by local German Swabians. Like vrah, even i would join the Chetniks or Tito's partisan's as well.
All the hate WW2 Balkan borders get with Hungary and Romania. Bulgaria and Croatia's were pretty great aesthetically and for giving each nation their max nationalist claims.
