Trump quips about Pearl Harbor when asked if Japan given advanced notice on Iran attacks: 'Wanted surprise'

President Donald Trump made a quip about Pearl Harbor Thursday when asked if Japan and other American allies were given advance notice about attacking Iran, saying the U.S. "wanted surprise." 

Trump made the comment while sitting across from Prime Minister of Japan Sanae Takaichi during a bilateral meeting at the White House. 

"Japan and the U.S. are very good friends, but one question, why didn't you tell U.S. allies in Europe and Asia, like Japan, about the war before attacking Iran?
