Jonathan Safran Foer said this quote

It is best if the guard is in love with America and wants to overawe the American by being a premium guard. This kind of guard thinks that he will encounter the American again one day in America, and that the American will offer to take him to a Chicago Bulls game, and buy him blue jeans and whitebread and delicate toilet paper. This guard dreams of speaking Englishwithout an accent and obtaining a wife with an unmalleable bosom. This guard will confess that he does not love where he lives.The other kind of guard is also in love with America, but he will hate the American for being an American. This is worst. This guard knows he will never go to America, and knows that he will never meet the American again. He will steal from the American, and terror the American, only to teach that he can.
