I was just thinking about this last night.
I can't pin down any specific POD, but if the Convention is able to stand its own against the Commune, then it could maintain order. Perhaps if the societies/clubs don't form; or if the King doesn't attempt to escape or give plans to the Germans, there won't be as much anger against them.
A shorter Terror may be more realistic. Intially, both the Girondists and the Jacobins supported the Terror, but after a few months the Girondists believed that it was time to end, as the major traitors had all bene dealt with.
With no Terror, the Revolution will be viewed betetr in other nations, especially America where it led to widespread repression even worse than the 1950s.
