It's a question that seems simple, but is actually complex. If France funds the American revolution, but it still fails, would the French Revolution still happen and lead to the rise of Napoleon?
Napoleon's rise was not exactly guaranteed even if there still was a revolution...
It will definitely be different. The US constitution, which had just been adopted, was a major inspiration. The Revolution effectively began when the Third Estate swore the Tennis Court Oath to not separate until a constitution had been written (and the document they ultimately produced, in 1791, was considerably patterned after its US counterpart).True. Even revolution itself could take lot of different paths in early stages like revolutionariers manage to push parliamentary system or republic takes much more moderate path.
