I'm not talking about dropping reparations altogether or anything like that. But taking into account lost lands, turned over assets, expanding the acceptable kinds of commodity payments, setting a fair gold value for these commodities, setting quotas that can be met, and greenlighting loans for economic reconstruction; all of these would be a huge boost to A-H's ability to pay.
Again look at what happened to Germany? Repeat with A-H simple that...everything else is wishfull thinking
The zeitgeist of the era revolved around the perceived strength of nationalism and the superiority of nation states. Feeling pessimistic about the future prospects of the Habsburg Monarchy was understandable given these assumptions. These assumptions however weren't necessarily warranted. The very much expected Bosnian Serb uprising in 1914 didn't materialise at all for example. The various nationalities were also much more reliable than many expected.
That was before 4 years of war, millions of death and crippled and an economy down the toilet with a political system that had lost any semblance of credibility; as said many many many times, the problem is not during the fight but once the bullet stop and you fully realize what happended and you have time to really think. The Empire had lost the biggest massacre know to man till that moment, there is no way that things go back peacefully as they were before like the Wien enstablishment want or the Magyarization effort like the big wig in Budapest want...all the minorities that had fought hard want to be payed back and nobody in the high place had the will, capacity and possibility to cover that price.
Not only that but there are new ideology that are spreading and are not very sympathetic with the current status of the Hapsburg Empire, not considering the civil war in Russia and the revolution in Germany that will spread in A-H making things even more volatile
The 1919 election results were abyssmal for Mussolini, even IOTL. It was the anti-socialist violence of the fasces that helped Mussolini to power, not the Fiume debacle.
Sorry but nope absolutely not, Fiume for Benny was like the Apprentice for Trump a way to make his name very famous and there were a lot of right wing faction that fight the communist and socialist and as i said, Fiume not only weakened the image and the perception of the liberal government but also was the blueprint for the march of Rome.
Another difference compared to Italy is the absence of liberal-catholic split. This gives the establishment a wider base to work with. As liberal ideas lose popularity, the establishment in Austria can much more easily shift towards more christian social policies. This could allow for cooperation and compromise with more moderate social democratic elements.
The Enstablishment had lost so much credibility that's not even funny, sorry but after losing tje war they will be politically deader than dead, nationalism and communism will be on the rise and the october revolution will weaken the moderate socialist on the movement and strenghten the more radical faction like happened elsewhere.
Why exactly? Wilson adocated for self-determination for the nations of Austria-Hungary, but them acquiring considerable autonomy the way I detailed above could still be seen as acceptable. If not else "hate with passion" sounds a bit strong to me.
Because Wilson will not find it acceptable and frankly his opinon is the only one that count at Versailles as neither France and UK will fight too much against him for that; Wilson basically humiliated an ally because he thought he was not entitled to land that were ethnically not italian image his opinion of an enemy that put a fresh paint of coat in an old building and whose survival is not assured and that basically the representation of everything dislike in the old order. He will go for destroying A-H probably not but don't expect any favor or mercy and in this situation Serbia and Italy will be supported by him.
Would they? ITTL Italy didn't break the Austro-Hungarian lines, so any prestige linked to that would be absent ITTL. Furthermore, Italy would still not get either Dalmatia or Fiume. The US objection to Italian designs on Dalmatia still would be the same, meanwhile Fiume would be deemed necessary for A-H to retain to avoid it becoming completely reliant on foreign(German) ports for its overseas imports.
Prestige is irrilevant, look at Greece and Romania, worse performance greater prize and better treatment than Italy; what's really important is the balance of power and the strategic consideration and while Wilson had objection to the italian design on Dalmatia, it had a lot less in weaking A-H and Wien is not in any shape to refuse anything; sure by OP and with the of ASB the front has not fully broken but the army is basically without any supply and the general food situation is catastrophic and the problem is not 'not obtaining Fiume and Dalmatia' the real problem at Versailles was the humiliation of the italian delegation by Wilson (and the Anglo-French) but in this situation there is no incentive in supporting A-H instead of Italy even because in this scenario more than imperialistic land grab looked more on strategic need.
Sorry, there is no way that A-H survive for long after losing WWI, expecially with a civil war in the east, a revolution in the north, nationalism spreading everywhere in the Empire and a political class and monarchy that had lost a lot of his prestige and credibility non including the millions of deaths, crippled and the economy destroyed. Why the Czech, the Romanians, the Croats want to remain in the Empire? What their benefit in this age of nationalism in remaining in a defeated and crippled nations that need so many reforms that once finished will be a totally different thing
