“This is what they exploited. They played the game as if they were immensely impressed by his personality and believed this is the guy who should be the president of the United States one day: it is people like him who could change the world. They fed him these so-called active measures soundbites and it happened. So it was a big achievement for the KGB active measures at the time.”
