How fares America in the eyes of the world?

John Winthrop exhorted his fellow voyagers that they would be “as a city upon a hill” in America. The “eyes of all people” would be upon them; they would be a magnet for the world’s imagination. Moral leadership of the globe, Winthrop is said to have announced, belonged to Americans by their very birthright.
