Is there any reason what so ever that Germany might invade Austria-Hungary in 1914, maybe in the defense of Serbia? POD can be before the turn of the century.
And, what are the effects? Do the German divisions cut through the Austrian border, liberating an independent Hungary and puppeting Austria? Are the Austrians (who did not have a particularly dazzling track record when it came to attacking Serbia) even able to hold the Germans back?
What is the opinions and actions of France; Russia and Britain from this turn of events?
