When Yugoslavia broke down, it was every group for themself, though some tried to keep things together. I don't believe the Serbs even bothered fighting for Macedonia, so why go for Slovenia? I suppose it might be a good excuse to get soldiers onto the other side of Croatia, but the Serbians didn't want all of Croatia, just the parts Serbs were in. Even if Croats were there. Just adding that since I expect someone else would if I didn't. Anyways, having Austria be even more flagrant with their denial of responsibility for the Holocaust (with many blaming Jews asking for their possessions back at trying to take advantage of the country) would help a little, though by 1990 it was seen as rather in the past. Need to find ways for the Austrian leadership to publicly scoff about the occupation of Slovenia during WWII. Maybe also have them as returning to the post WWII complaining about the Italians getting South Tyrol back (I imagine most Austrians generally just stayed quite about the whole thing since four countries were occupying them). Perhaps some records of corruptoin in the Klagenfurt plebiscite can be found? When it was revealed that the British representative to the Venezuela-Guyana border dispute had told the American one they already bribed the neutral representative (thus the American and Venezuelan{not sure if they were represented, actually} went along with the current border to avoid the tribunal giving more land to the British) leading to Venezuela reopening their old claims. Frankly, I always think the Slovenes got the short end of the stick in Yugoslavia for territory. Anyways, how about we have the Austrians rattling sabres about northern South Tyrol, the Yugoslavs never giving up their renewed claim to Klagenfurt after the war, plus something with Trieste. And of course changes need to be made to the acceptance of the Austrian government to Slovene language institutions. Perhaps they also reclassify some Slovenes as Wends? None of this is especially realistic, especially without working from WWII onwardto change the mood.
