Austria has most of the Trent region, you should compare a 1914 and 1919 map and the difference will be clear. As I said, Italy has a very small piece, but that's it. Austria and Germany might partition the Sudetenland, but in this map the border with Austria (and from what I can see of Germany) it is the same as otl. I wonder if Kaiser Karl will make a bid to reclaim the Hungarian throne and be successful with the resources of Austria behind him? That being said, maybe he would make sure one of his children would rule, with a proper regent in place until then, and someone alot more worthy than Niklos Horthy). I don't think either the Hungarians or the Austrians would want to resurrect the Ausgleich.
