My parse is, the USA is founded on documents and philosophy instead of the personal power of a string of hereditary leaders and/or their overthrowers. I also feel the comment ignores the nuance of the fact that France's claim to be "An" enlightenment nation, if France wanted to make such a claim, is not so different than that of the USA just because France might be on its 5th Republic. How long has the L/E/F motto been the motto of France or French citizens anyway? The other side of that nuance being that perhaps French nationalism has a different flavor because it could be about different forms of nation at different times.
