Suppose Karl of Austria somehow comes to the Austro-Hungarian throne without WWI. Perhaps both Emperor-King Franz Joseph and Archduke Franz Ferdinand die earlier in the 1910s or they die on schedule but alt-WWI is pushed back a few years. How would Karl's rule look without a world war going on? What were his plans for the empire? Can he keep it together and deal with Hungary? He was a peacemaker during the war, involved in the Sixtus Affair, and supporting the Pope's attempts to make peace? Could he delay alt-WWI further? Could he declare Austro-Hungarian neutrality in such a conflict?
