I had read that the Austro-Hungarian Empire's economy was actually increasing in the years up to World War 1, and the country was industrializing at a steady pace.
I'm wondering if it's possible to keep Austria-Hungry around until World War 2 (or, in case World War 2 never happens, to around 1941). It can survive long after that if possible, but I want an AHE around at least until then.
Oh, and similar borders. It doesn't need to be wanked-out, but it can't turn to a shriveled husk either.
