Would the French Revolution still happen without an American victory?

Would the French Revolution still occur if the American Revolution failed?

Probably, because the French conditions remained, but it might begin later or under a different monarch.

A French revolution remains possible even if the American Revolution fails. The underlying conditions in France remain, although one external example and source of momentum has changed. The rupture might occur a few years later or under the next monarch rather than on the historical timetable. Timing remains uncertain, but American independence was not the sole cause of French upheaval.
