How did the French Revolution affect American politics?

The French Revolution had no direct effect on the United States. A new country, the US had sufficient teething problems organizing and financing their new democracy, and the turmoil in France had no effect. However, after the Revolution, when Napoleon returned to power and fought the English, it gave Jefferson's reconstituted US Navy the opportunity to support the US Marines in the early fight against the Barbary pirates in the Mediteranian.
