The counterfactual does not automatically stabilize Austria-Hungary. Germany entered the crisis after Austro-Hungarian mobilization against Serbia helped trigger Russian mobilization, so a rapid German collapse leaves the original dispute unresolved. Vienna could be brought to the peace table and Russia might gain concessions without the same prolonged fighting. The empire could still fragment through its own internal conflict. A short war removes one path to destruction while leaving the Habsburg state's structural tensions in place.

A short war does not solve Austria-Hungary's instability
German collapse can force Austria-Hungary to a negotiated peace, but removing four years of war does not remove the multinational empire's internal strains.
