Why would nations other than Britain care about the outcome of the American Revolution?

The reason why other nations besides Britain would care about the outcome of the American Revolution because it shows that even the Continental Army which was a small group of untrained merchants and farmers that had no navy or proper weapons could still beat the powerful british army that was properly trained, that any other army in this globe could beat them, like the Americans. Plus it shows that we (Americans) will fight for freedom and indenpendence, and that no one ( any country ) can't power us.
