so basically the "best"( not a good term isn't it?
) third Balkan war scenario would be have Yugoslavian forces , pissed of by Albania insurgents, to invade Kosovo and Macedonia, making Bulgaria join for Macedonia ( thus increasing the pro-Bulgarian sentiment i believe). The Greeks make their protest more heavy by threatening to stop commercial access for both Macedonia ans Bulgaria to Thessaloníki ( in OTL they Blocked access to Macedonia) which in this scenario might convince Grigorov to accept a unification with the Bulgarians( maybe with some autonomy like the Italian special statute regions?) while also allowing the Albanian minorities to join Albania.
-Greece gets praised for helping solve more peacefully a war
-Yugoslavia might do some initial offensive but retreat and admit the lost while trying to keep Bosnia or risk to have a 2 front war with a nation that in the 90's has not fully lost it's military strength ( Bulgaria was heavily demobilizing in that years but a war against a weaker yugoslavian army should still be winnable)
-Bulgarians have a new national holiday as they finally reclaimed Macedonia after losing 3 wars in a row
-Albania also makes their dreams of Great Albania by annexing Kosovo and some pieces of Macedonia .
is that all or did i forget something?
also, depending on how Yugoslavia acts Bosnia might have a better time than OT, right?
