Mr. Trump is an expert at manipulation.  He tweets from the hip because he is aware that his reaction to something newsworthy must be quick and loud for people to react.  We live in a time when most have very short attention spans because we are constantly bombarded by news and information.    This president is not concerned about the parsing of intelligence reports, or worried about media dissection of his comments, couldn't care less because he knows that he grabbed a headline, and that is all which will be remembered.
