Trump also said Hillary is not fit. He does have a crystal ball.
I’m thinking of Greek Mythology and the story about Cassandra.
The god Apollo fell in love with the human Cassandra and gave her the gift of foresight in an attempt to woo her. But she spurned him anyway, so he cursed her and made it so no one would believe her predictions.
Cassandra always knew what would happen, but no one paid attention to her. She told the Trojans about the horse — but they brought it into the city anyway.
Trump's predictive skills remind me of that great TV show, The Mentalist. The show's theme was that a guy who was raised in a carnival sideshow and grew up to be a "psychic fortune teller" consults with the California Bureau of Investigation, and later the FBI, after his wife is murdered, to help solve crimes. Throughout the 7-year run of the show, he denies really being psychic or even that psychic powers actually exist; instead, he is very perceptive and observant of small details and very intelligent in deducing what these clues add up to.
With regard to Osama bin Laden and terrorist attacks, Trump as a NYC-based builder of towers had to be gravely alarmed and highly alerted the first time the jihadists hit the underground parking garages of the World Trade Center in 1993. From that incident, a NYC tower builder with a reputation for intelligence and perception of small details would naturally have been sensitized to any news stories related to that threat and its possible sources—far more deeply than most people.
