While reading through threads on the collapse of Austria-Hungary after a CP victory i noticed the majority feel Germany would intervene and a great number of people believe Germany would absorb the "German" territories.
Well, that got me thinking. Let's say WW1 doesn't break out like in OTL. FJ dies on schedule and the Ausgleich of 1917 breaks down into revolt/revolution.
Serbia and Romania would be chomping at the bit to intervene, how would Bulgaria react to the Serbians and Romanians being occupied to the North.
Would Germany, or any other Great Power (looking at the Czar) intervene? What would the ramifications of that be? France certainly could see Germany occupied to its south and make its move, GB would almost definitely be strongly against Germanys growth south, but would it be as wary of Russian growth west?
