What would happen if the Austrians decided to call their bluff by saying fine but that they're keeping Transylvania and Croatia-Slavonia, or at the very least Croatia-Slavonia, is they want to go off in a huff?The fact that the Ottoman Empire wasnt infected by "this christian nationalism thing"by 1914 doesnt mean it will never be; and Austria-Hungary was doomed to collapse the next time Hungarians decided they wanted to blackmail the empire to become the ruling nationality.
