Depends on your definition of "the United States".
If you mean the current government, absolutely they can't lecture anyone on democracy. They are authoritarian oligarchs, tyrannical communofascists.
If you mean the Nation, the People, the Idea, The Vision of the Founding Fathers that humans are granted rights by their Creator and born free to chart their own destiny, and that all government is by its nature EVIL so it must be constrained to the maximum possible degree, then fuck off, nobody has ever done it better.
