What if Bulgaria and Serbia had not gradually seen a souring of relations during the First Balkan War, planting the seeds for the second conflict? I’m relatively unknowledgeable about the conflict, but one possible PoD from Wikipedia seems to be the Bulgarian censor not cutting mention of the Serbian participation in the capture of Adrianople from public record, which IOTL caused a major diplomatic scuffle that eventually led to the Second Balkan War.
I know the Bulgarian-Serbian conflict was not the only reason behind the second war—Bulgaria wanted more of Greek Macedonia, for one thing—so is there a different PoD that would work better? If not, what would the effects be of the specific PoD mentioned above?
BIG EDIT: Can this be moved to After 1900? Whoops, lol
