What if the French Republic falters militarily and the Prussians and Austrians are militarily successful to one degree or another?
Apparently, as the Prussians defined the war aims, they were seeking to break off Flanders for Austria and Alsace for Bavaria and maybe Austria, with Prussia gaining some land from Bavaria and Austria in compensation.
Could the French Republic begin its history as a partly territorially shrunken domain (like the USSR).
Or would coalition members be irrevocably committed to restoring the monarchy and Ancien Regime?
If they somehow succeed in restoring the Bourbons, how many years till even Bourbon France moves to reclaim Alsace and Flanders?
