At the press conference following his meeting with North Korean leader Kim Jong-un in Singapore on Tuesday, President Trump called himself “an emissary of the American people” and spoke of “my instinct, my ability or talent” for negotiation. “My whole life has been deals,” said Trump. “I’ve done great at it.” Trump is indeed a skilled salesman, and his presentation of the new U.S.-North Korean denuclearization agreement is a fine sales job.
