First mention of America I've spotted, and it sounds pretty accurate to call it the sweepings of the rest of the world.  Like, if international influence were a smell, America would be what happened when you threw all the gross stuff in a barrel and let it sit there for 200 years.  It would just overtake everything else. (Note:  It's super-fun to be sarcastic about America, but I don't consider myself especially well-equipped to evaluate countries, and America definitely has its good side.)
